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.

Cock Off

Coigned by Bubba the Love Sponge: When two males that cannot settle an argument or dispute in any other civilized fashion resort to measuring their genitals to determine a winner. The standard form is to lay your junk on a table about yea high while your opponent does the same from the opposite side. The match is immediately forfeit if you attempt to touch your opponent while he is in this position.

Bubba and Ronny had an dispute that they couldn't settle. Bubba challenged Ronny to a cock off. When they measured their cocks, it was determined tht Bubba's cock was longer....He was then named the winner of the cock off and the argument. ...and there was much rejoicing

cock off

Functions in the same way as 'fuck off' or some other expletive which expresses disdain at another or a desire for them to leave/stop talking/stop messing around.

Colin: "You know, Nadine, some people think that buildings like my garden shed are actually rather attractive."

Nadine : "Cock off, Colin."
