A variation of the infamous "Donkey Punch", Donkey Basketball is when you're engaged in anal sex and at the moment of ejaculation, you slam the receiver's head repeatedly into the wall or bed (for the beginners) similar to dribbling a basketball. If done correctly, the receiver's anal cavity will tighten, their body will convulse, and a concussion will be imminent. This will allow you to orgasm in a spectacular fashion.
Why is there a backboard over your bed? For Donkey Basketball.
This is the fourth Donkey Basketball related death this week.
