Cock Blocker 

A cock Blocker is a person close to you or of just general aquaintence who prides him or herself in screwing up your chances of getting a sexy time with a girl you're trying to get with. He or she does this by saying wildly innappropriate things about you or your potential sex partener. Or by just making the situation awkward by doing something stupid to either or both people. This block's the boy's cock from getting in a girls's smock.

1."dude, did your friend just slap my ass?"

"he's not my friend anymore (goddamn cock blocker!)"

2. jack is cuddling with jill and jimmy comes around the corner. jimmy says as he passes by: "hey jack, how's your aids?" jill says: "you have aids? maybe we shouldn't do this" jack says "ima kill that sonofabitch"

a person who truly stops at nothing to prevent another (usually a male) from getting any type of burn.

when sean saw that mahsul was getting too much burn he initiated the cock blocker 3000 (a.k.a Max) who then approched Mahsul and asked him for the hw... while he got it from his bag max began talking to the girl.... max then left with mahsuls hw, his girl, and his dignity.... the encounter ended with mahsul calling max a cock blocker.

Cock Blocker 

When assisting a customer at a retail store, getting your sale on, and the girlfriend comes and says, "you look gay." Your sale is gone. You've been cockblocked.

As soon as I got him to put on one of those $500 shirt, his girlfriend totally cock blocked me. What a bitch.
