The act of "measuring up" with another man. It happens when two men (usually drunk or high) will start to argue about penis length. It happens when one man pulls it out and lays it on a table. This is the challenge stage.
When the other man lays his out and both penises are measured, it is said that the winner has longcocked the loser. He will then collect his spoils, if there were bets placed.
"Old Harry was out longcocking at the pub last night. He won three drinks before the cops took him home."
"After Dave longcocked the police chief, he was never given another speeding ticket again. The chief kept his longcocking habit on the down low for a few months after that."
Noun. An act usualy performed between a married couple, not high school fags like all of you. See as follows:
When I laid the ol' pipe-work the other night, and stirred it around deep like a roto tool. She made that cute noise, and then high-fived me for my trouble. She didn't try to make me cuddle because she knows I fucking won't. I slapped her on the ass, cause she's an alright broad, and that's how I let her know that she's tits in my book. You know, and then maybe she makes me a sandwich or something to say thanks for that deep dickin. That was a motherfucking pimpy longcocking, and she knows it.
I'm dead serious.
She's a good girl, and not a feminazi hosebag donkey raping fatty. I'm gonna give her a good ol' PIMPY LONGCOCKING. I'm gonna own that shit.
