This is the verbal/metaphorical comparing of dicks, most often by two men. It usually involves things that cost a lot of money, such as cars, boats, or any sort of monetary investment.
Used by Liam Neeson in the movie Taken.
Man 1: My boat is 42 feet long.
Man 2: My boat is 51 feet long.
Man 1: My car is worth $66,000.
Man 2: My car is worth $74,000.
Man 1: I banged your wife.
Man 2: I banged your brother.
Man 1: Uhhh... I think that's enough dick misering for now.
