Large amps at a party, that people climb up on and start dancing, while the beat and music pump out of the speakers beneath them. Usually a fun, but slutty attention seeking practice aimed to pump up the crowd by shouting the lyrics at them, preferably done after drinking quite a bit of alcohol.
Girl/Guy: I love this song! I'm getting up on the Slut Boxes so everyone can see my moves.
Friend: Wanna see how many people we can get on it?
