Cock-off 

An event much like a duel, where two men unable to come to terms by conventional methods such as talking or fighting, stand back to back, walk 10 paces, turn and drop their pants. The man with the largest cock wins, and the loser must hang his head in shame and leave.

Obviously talking or even fighting wouldn't have settled the argument so I challenged him to a cock-off. I won.

Cock-off 

Two men use the barometer of manhood to win a duel relating to who has the strongest masculinity.
A win can be attained without the need for a showdown (similar to poker)

Two geezers in a pub toilet. A clubber and a long haired Iron Maiden Man. A cock-off ensues.

Clubber: "Feeling insecure there m8?"
Mr. Iron Maiden Man(slightly confused look): "a-NOPE"
Small pause.
Clubber: "you should be"
Mr. Iron Maiden Man(slightly annoyed & definitely agitated): "Yeh - any time you want mate - bring it on"
Clubber finishes and leaves, Iron Maiden Man wins.
