SlutWalks in Latin America were renamed "Marcha das Vadias" in Brazil and "La Marcha de las Putas" in most Spanish-speaking countries, sometimes using PUTAS as an acronym for "Por una transformación Auténtica y Social (For an Authentic and Social Transformation)" Some countries like Argentina, Brazil, and Colombia were known to host simultaneous Slutwalks in different cities. In almost all countries, Slutwalks are repeated annually, although not always in the same cities. Some protests select their dates to match significant events such as the International Day for the Elimination of Violence against Women and the World Youth Day.
There were some interactions noted between the organizers in different countries. Organizers from Argentina had previously contacted their counterparts in Mexico and Venezuela through social networks, and artist Adriana Minolitti participated in Mexican Slutwalks before becoming an organizer herself at Buenos Aires. They were, in turn, contacted by organizers in Bolivia and Uruguay to get assistance. Also, the organizer of the national Slutwalk at Colombia had some previous interaction with organizers in Peru, and Argentine activist Leonor Silvestri travelled to Chile to help organize La Marcha de las Maracas in Santiago. In most countries, the LGBT community actively participated, and many protests were attended by sex workers, with others expressing their solidarity. There was also a common regional chant: "!Alerta, alerta, alerta que camina la Marcha de las Putas por América Latina!" (Alert! Alert! Alert, the sluts are walking to Latin America!).
The Latin American protests shared the same purpose as those in other continents, but were additionally directed at local state authorities and members of the Catholic church whose public comments they saw as reinforcing gender stereotypes and a culture of violence against women. Protesters wore Catholic costumes in several countries, while many protests demanded a secular state and blamed the Catholic church for holding back women's rights. There were some exceptions like Colombia, where Catholics joined the protests. The Marcha das Vadias against the public spending for the visit of Pope Francis in Copacabana, Brazil, featured dissident Catholic groups marching among the protesters as well.
Some protests evolved into permanent organizations, continued working throughout the year to combat violence against women, and participated or organized events other than the typical SlutWalks to raise awareness on sexual assault.
Argentina
On August 12, 2011, the first SlutWalk took place simultaneously in Buenos Aires, Rosario and Mar del Plata, under the name "La Marcha de las Putas". The organizers, most of them belonging to women's and human rights organizations, described the march as "not a strategy to fight, but a union of women and men to demand respect for the individual liberties of women." Participants mentioned the alarming rates of murdered women and human trafficking for sexual exploitation in Argentina as motives to join the SlutWalk. Feminist deputy María José Lubertino, who participated in the protest, said: "Even though it started in a foreign country, this march helps us build a better citizenship and that is what pushes public policies forward." On November 25, 2011, La Marcha de las Putas protested in the city of Mendoza. The day was selected for being the International Day for the Elimination of Violence against Women. A document issued by the organizers states: "we will march to demand an end to all forms of violence against women, the figure of femicide as aggravation incorporated into the penal code, budget for the implementation of the Domestic Violence Act and the processing and approval of the law for voluntary interruption of pregnancy.
New Marchas de las Putas were held in Buenos Aires, Córdoba, San Juan and Mar del Plata on November 3, 2012. The main theme for the protest were sexual stereotypes. The march began with an exposition of photographs from the previous rally. There were also workshops and debate spaces regarding intimate and social respect, non-sexist education and media violence, while several music bands performed on stage. Organizer Verónica Lemi explained: "marching is not enough. We need to raise awareness and create spaces for reflection and debate so we can take our slogans to our daily lives. We need society to stop justifying, tolerating or minimizing sexual abuses, and to stop victim-blaming." She also pointed at the need to promote that "sexual abuse survivors speak of their experiences without being judged for it, and get the help they need to heal." The objective of the protest was to re-signify the word "puta" (equivalent for "slut", but also for "prostitute"), to take its violent power away so it cannot be used to cause harm, to favor the construction of a society where everyone is respected regardless of gender, sexual orientation or chosen lifestyle.
On October 6, 2013, another Marcha de las Putas took place in Buenos Aires. It began with an open space for sharing experiences of abuse, most of which had happened to the speakers during childhood or as teenagers, and kept silenced during years. "It took me twelve years to tell my family I was abused when I was 10. I only was able to do it after I joined this movement and found other people went through similar situations" explained Deborah, one of the organizers. Rita González, other of the organizers, explained the march is framed in a wider range of "actions done during the whole year, to give legal assistance, emotional support and company to people who have been through difficult situations, which they begin to overcome in healing encounters where they can verbalize their pain." The selected slogan for the protest was: "Desnudando la cultura de la violación (Disclosing rape culture)". Other cities known to host Slutwalks were Posadas, La Plata and Formosa.
María José Lubertino, once again participant of the march, said: "in the 21st century, we cannot allow women to be judged for how we dress. A few weeks ago our President Cristina was discredited for wearing leggings, a clear example of what we see in a daily basis in different spheres. It's ridiculous and a typical patriarchal behavior. La Marcha de las Putas is about getting actively involved in building a new reality, in which respect, recognition and effective equality between men and women prevail."
On November 19, 2013, La Marcha de las Putas participated among several other organizations in a wider protest to raise awareness on child sexual abuse. It included activities related to the importance of detection and prevention of child molestation, legal processes, and healing. The protest advocated for better laws, and for the effective application of the existing laws. The day was closed with speeches from the organizations, and artistic activities for the participants.
Brazil
The first SlutWalk took place in São Paulo under the name "Marcha das Vadias" (also "Marcha de las Vagabundas") on June 4, 2011. Around 300 people gathered, marching in daily outfits. Only a 23 years old student participated in underwear. The organizers of the event, writer Solange De-Ré and publicist Madô Lopez explained: "We do not want Carnival. We want people to dress normally, as they like to wear." On June 18, 2011 a new Marcha das Vadias gathered one thousand people at Brasília. Despite the name, the SlutWalk brought together women, men and families, sometimes including babies. Participants chanted slogans against sexual abuse. On July 2, 2011, hundreds of people attended Marcha das Vadias at Copacabana, in the South Zone of Rio de Janeiro. Participants advocated for the improvement in hospitals and police stations for women victims of sexual abuse, access to abortion with no paperwork when pregnancy is the result of rape, and the effective implementation of the Lei Maria da Penha, in cases of battered women. During 2011, new Marchas das Vadias were organized at Belo Horizonte, Florianópolis, Juiz de Fora, Recife, Fortaleza, Porto Alegre and Natal.
On May 26, 2012, Marcha das Vadias took place simultaneously in Brasília, Rio de Janeiro, Belo Horizonte, São Paulo and Vitória, among others. During the march in Brasília, a man participating in the protest began to speak offensive phrases to women and homosexuals, and then dropped his pants to show his penis. He was quickly arrested and taken to a nearby police station.
On May 25, 2013, Marcha das Vadias was held in Recife and São Paulo, gathering over 2000 and 1000 people respectively. Késia Salgado, organizer at Recife stated: "The march is to show that women will no longer be silent, that impunity will not happen; we live a social epidemic and have to reeducate ourselves. Marcha das Vadias does not end when the protest is over, we keep working so that daily violence is not forgotten." In this city, the protest included various artistic interventions of groups supporting the cause. Towards the end of the march at , the group opened space for testimonials. With megaphones, women victims of sexual assault shared their experiences with the rest of the participants.
In São Paulo, the march walked past rue Augusta, a street known for being a gathering point for prostitutes, as a gesture of support. "It's in Augusta where we find the women that society likes to call sluts, or rapeable" explained a member of the collective. "Our intention is to create visibility on the fight against violence towards women. We want to encourage women who are suffering violence to break the silence and make men aware of the daily acts of violence they practice." Protesters also handed over to pedestrians a "security card" to be kept in wallets, containing the phone number of services which help abused women.
There was a new Marcha das Vadias organised at Brasília on June 22, 2013, gathering around 3000 people. Protesters spoke against the State intervention on women's bodies, and against religious leaders occupying seats in State institutions. A new episode was reported of a man who, in apparent state of drunkenness, insulted the manifestants and dropped his pants.
In Copacabana, Rio de Janeiro, Marcha das Vadias was planned to match a visit from Pope Francis to the city, on June 22, 2013, in the context of the World Youth Day, and the protest was renamed "Jornada Mundial das Vadias (World Slut Day)". Organizer Rogéria Peixinho explained "performing the act during the Pope's visit is also a way to put another youth on the street, establishing a political counterpoint. We want to show that there is another youth and another way of thinking about the world, and the chosen date also has to do with it." There were several participants in costumes representing religious characters such as nuns and the Pope, and signs with puns and slogans rejecting religious views on women and sexuality. A group called Católicas Pelo Direito de Decidir (Catholic Women for the Right to Choose) in favor of abortion, women priests and married priests, participated in the protest.
Peixinho asserted the importance of the Pope's visit regarding the objectives of Marcha das Vadias: "The presence of the Pope and the public resources allocated for the visit of a spiritual leader calls into question the secular State. (...) This matter falls within the axes of our movement, as well as the right to the body, the complaints about the rape cases that are increasing especially in Rio, and the formulation of public policies to protect women." The participants, during the march, encountered a group of about 50 pilgrims from France, Chile and Italy, participating in the World Youth Day, who were offended by the act and started insulting the participants. A pilgrim spat in the face of a protester. However, most pilgrims peacefully observed the demonstration and some foreigners, without realizing it, mingled among the protesters.
