关于此声音
This is a three-second Portuguese vocal line from a Raimundos song, built around the phrase in its title. It feels playful and cheeky, like a dare tossed out in the middle of a joke, and it works best when the listener already knows the lyric. The clip comes from a song by the Brazilian band Raimundos.
