Tiger Clause 

A homosexual sex act designed to mimic the mating ritual of the siberian tiger. The "top" will insert himself into the "bottom" and lay on him, completely motionless, while ferociously biting about the ear and neck of the "bottom".

"I got the tiger clause from John Doe last night and had to call out from work today."
