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"
