A game commonly played in college and the military where participants try to get their opponent to look directly at their asshole.

Typically, a participant will try to surprise their opponent by hiding somewhere bent over with their ass cheeks spread. When the person walks into the unsuspecting place he/she is overwhelmed by the sight of the orifice.
Our blackholing game is on this month! I'm up 4-2. I blackholed Jim real good when he walked into his dorm last night. I was standing on his desk bent over and he nearly collapsed when he turned the light on.
