The act of blocking someone else's cock, by stealing one's chances of getting LAIDDDD!
When Rachel Akiva and Bryan were all at 7-11, Bryan was hoping to get in the sack with Rachel. But evil fat Akiva cock block ed his overtures, and Bryan was left high and dry. And Rachel was not the least bit interested in Akiva's puny cock which was inversely proportional to his immensely troll-like feet.Fuck akiva fuck akiva

Preventing a fellow male from tapping ass when hes going down the stretch. A man can cock block inadvertently but it is often done out of jealousy or asshole-ism.
"That loser couldn't get a chick for himself so he decided to hang around like a third wheel and cock blocked me instead."

Friend who maliciously prevents the act of getting booty.
At the club, Patrick was about to get Bianca's phone number, when Al (ie the Closer) cock-blocked him by telling her Pat’s a nice guy… that lives at home… with his parents.

Anyone or anything that gets in the way of you getting some. The cock-block can be male,female, or inanimate. Many cock-blocks can't get any themselves so they try to stop somebody else. If they ain't scorin' nobody's scorin'. No scene is too embarassing in their undying quest to prevent your action. If your buddy's a cockblock don't bring him or her.
1. My old boss, Bob is such a cock-block. He won't let any of us guys chat with the female employees.

2. My car was a cock-block. It broke down on my way to the party so I couldn't go and possibly hook-up. I had to wait for the tow-truck to come and tow me home.
