Umbigada (from Portuguese umbigo, "navel"), sometimes translated as "belly bump" or "belly blow", is a dance move in various Afro-Brazilian dances. It is seen as a "basic feature of many dances imported to Brazil and Portugal from the Congo-Angola region", for example, samba, fandango, batuque, creole drum.
It is performed as follows: a dancer opens her arms and extends her navel towards another dancer. The bodies of the two dancers may, or may not touch. Waddey 1981, p. 255.
It is commonly used as an invitation to dance, e.g., during samba de roda ("samba in circle"). However it may also constitute an element of the dance itself."A UMBIGADA EM FILEIRA", Jangada Brazil, no. 40, December 2001 Chapter XXII: Umbigada (pp. 130-141 in: Luís da Câmara Cascudo, Made in Africa, pesquísas e notas, 1965, and later editions (CÂMARA CASCUDO, Luís da.
