A Heat Sink is when a homosexual policeman pulls out his police truncheon sets it on fire and procedes to insert it up another policeman's bottom.
A Heat Sink scenario,

Policeman 1:
"Excuse me, do you have a light?"

Policeman 2:
"Hey sure, use my lighter. By the way, why do you have your truncheon out?"
