Chair Rave, is where, if you're listening to music whilst on the computer, and you're sitting down, you cant help but have a rave
to the music.
Similar to a Chair Boogey :)
... but better!
person1: did you see person3 chair raving
person2: Yeah, what a strange person he is.
person1: I know, he should really learn how to rave
properly, not Chair Rave.
