cock block

The act of interfering with a friends plan to have sex.

Knowing that speedbag would be getting his going to Vegas blowjob the morning he was leaving, his good buddy thought it would be funny to cock block him and showed up at his house to pick him up 15 minutes early for the second year in a row.

cock block

to prevent a friend from hooking up with someone, maybe because she's too drunk or perhaps because he is supa busted. it could be the other way around too.

"Sweetie, I'm going to have to cock block here. Homie looks mad busted and I know you don't want to wake up in the morning thinking 'What The Fuck'."

cock blocking

the third type of blocking in football (when the game is on the line and you need to give the QB more time than run or pass blocks can allow) where a lineman pops a viagra, making sure the defender notices the easily identifiable buldge, so that said defender will lose all motivation to have any contact with the offender, giving up for the remainder of the play.

Cock blocking. *pushes right arm forward while left hand grabs genitals* Offense. 15 yard penalty. Repeat 4th down.

cock blocked

Preventing some unsuspecting moron from getting laid one night, or possible ever.

A kid walking with some chick in a parking lot gets soda thrown all over him by people driving by in a car. Therefore, he isn't getting any of that pussy that night. Or ever.
