Thor's Dick
A type of wager or dare in which the stakes are extremely high but only apply one person or party. The purpose of the Thor's Dick wager is to flaunt one's ego or ability. If the party in jeopardy loses and fails to live up to their end of the bargain then it is not a legitimate Thor's Dick wager, and the guy chickening out on his punishment is a tool.
Jordan decided to wage a Thor's Dick, saying that he would run down the street with no pants if he lost this game of ping pong. After losing, he lived up to the agreement and the Thor's Dick wager was completed.
