Deize Tigrona is a Brazilian funk carioca musician. Born in the São Conrado neighborhood of Rio de Janeiro, Deize worked as a house cleaner until her music career became successful. Her song “Injeção” was used as the basis for the M.I.A. song "Bucky Done Gun". Recently she has performed both with M.I.A. and with another popular funk carioca singer, Tati Quebra Barraco.
While funk’s lyrics often focus on relationships and sex, and many male funk carioca artists commonly objectify women, Tigrona has received some criticism for some of her lyrics. Although she has a relatively low profile, her song "Injeção," which translates to the English word "injection," had some success, and includes the lyrics Quando eu vô ao médico, sinto uma dor / Quer me dar injeção...Injeção doi quando fura which roughly translate to "When I go to the doctor, I feel a pain / He wants to give me an injection... The injection hurts when it penetrates." The song, which incorporates many other sexual metaphors, samples the horns from the theme of the Rocky films, "Gonna Fly Now." Alex Bellos has noted the key characteristics of this genre as "Coke. Guns. Booty. Beats." - the last two of these can certainly be heard in Tigrona's song. Funk carioca, when played in its typical, extremely loud, floor-shaking style, often has the effect of "going straight to the booty," says funk researcher Greg Scruggs.
