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'."

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.

"Icing" -- or "getting iced" -- is a frat star drinking game. The rules are simple: If a person sees a Smirnoff Ice, he or she must get down on one knee and chug it, unless they happen to be carrying their own Smirnoff, in which case they can "ice block," or refract the punishment back onto the attacker. However, an "Ice-block-Re-Block" is when the original attacker is in fact carrying two Smirnoff Ices and anticipates getting Ice-Blocked. In this scenario, both players must get down on one knee and chug it, hereby putting an end to the game (to avoid further blocking).
Me and my coworkers were away at the cottage this past weekend. Things got really intense when I tried blocking Enn's attempt to Ice me. It turned out he was ready for it and I fell victim to an Ice-Block-Re-Block.

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.
