Erva Venenosa is a song by Brazilian rock singer Rita Lee, whose playful take on a poisonous herb became a well-known part of her catalog in Brazil. The title translates roughly to poisonous herb, and the lyrics use that image for someone charming but harmful. Online, the short chorus is shared as a sound for gossip, drama and fofoqueiro jokes, with Portuguese tags linking it to talking badly about others and neighborhood babado. Its catchy retro melody and instantly recognizable vocal keep it in circulation for memes, reaction clips and short videos about sly or troublesome characters.
