When people whom have cars load a ton of people in the aformetioned cars in order to go to a party. Then when they get there the party is either cancelled or they are waiting for the okay to go in. So they let everyone out of the cars, turn all the radios to the same station and blast the music at max volume. Usually resulting in the car being damged/danced on/ used for sex etc. etc.
Person one: Man, that cast party
was bonkers! We car raved until the cops showed up
Person two: My car got totalled and raped, but oh hell, it was awesome as fuck
