This is an event that happens every so often during the summer season in a beach town when your under 21 and there is nothing at all to do. This involves driving around in a car (preferably one with a good sounds system) with a group of your friends at night when the streets are full of shoebies. Everyone in the car must be wearing aviator sun glasses as you blast 90's dance music. The job of everyone in the car upon pulling up to a group of people, is to stare at them while keeping a strait face. Party car is achieved when the people outside of the car start to dance.
Dude I'm bored, i think its time for party car
