When a couple of people pile in a car and drive around on country roads drinking beer. This usually is done on the way to a party or waiting for a party to start. This is most enjoyable when women are involved. Another good idea is to make a power hour mix where a song plays for 60 seconds and a siren goes off signaling everyone in the car to take a drink/shot. A full tank of gas and a couple different power hours can make for one long night you may never remember.
Bob: Hey is there anything going on tonight?

Steve: Nope, not shit, wanna call up some women and road trip? I'll pay for the gas if you buy the beer.
