The band's name was originally Bacilos Búlgaros, a literal translation of bacilli, named after a home remedy touted by Villamizar's grandmother. It is also a play on the Spanish language word "vacilón," meaning a fun, good time.

Although based in Miami, Villamizar considers the band to be a "Latin American band" and the band has had several number one hits in Latin America.
