The drinking game in which a person with a full cup of beer (generally cans or bottles are not as effective) sits in a computer chair or preferably a taller chair (maybe one at a bar or kitchen counter) that spins 360 degrees. The chair is spun as fast at their friends can spin it, and the drink is then chugged while spinning. Meanwhile all the other people in the room are yelling or cheering or whatever to amp up the level in the room. The person is allowed to get up from the aforementioned chair when the beverage is fully consumed, but the chair is not allowed to be stopped until the beverage is consumed as well.
We played spin and chug last night. It was awesome.
