A Chinese Cock-Trap is when two males get so intoxicated (the only way this would be fathom able) and decide to play this game. One male inserts half of a Q-Tip in his erected penis then the other male shoves the other half in his erect penis. Then in one motion both males thrust backwards: the male with the Q-Tip remaining in their penis is the declared winner.
Dude, Crist and Matt got into an argument the other night while they were drinking. So they played Chinese Cock-Trap and Matt totally pwned Crist.
