The practice of holding a hand out the
window while driving at high speed and "
cupping" the oncoming
air as though it were a boob.
HMB: Hey, mind if I open a window?
DTM: Sure. Did you
fart?
HMB: No, I just want to grab an air boob.
DTM: Ahhh, yes. Air boob time!
HMB: AIR BOOOOOOOOB!
(Both roll down
windows, grab air boob.)
DTM's
dad (confused): ..."air boob"...?
