Cockoffs can also take place in a dudes backyard....perhaps at some sort of celebratory cook-out.
Blake: With utmost heartfelt respect, I disagree.
Weasel: Why don't we cockoff then?
Blake: I'll go get the brand new ream of plates I just bought.
Nadine : "Cock off, Colin."
A win can be attained without the need for a showdown (similar to poker)
Clubber: "Feeling insecure there m8?"
Mr. Iron Maiden Man(slightly confused look): "a-NOPE"
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.
"If you cock-off to me again, I'll mess you up!"
"Cocking-off to a cop will only land you in jail."
