лил джон turn down for what

The phrase "Turn down for what" is a slang expression popularized by the song of the same name by DJ Snake and Lil Jon. It essentially means "Why should I stop partying?" or "Why should I calm down?" The term "turn up" refers to partying and getting wild, so "turn down" means to stop or reduce the partying. The phrase questions the reason for stopping or calming down, implying there is no reason to do so—it's a call to keep the energy and excitement going. It has a rebellious and celebratory tone, often used to hype a party or situation where having a good time is encouraged.
