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"

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.

Power Cock-Blocker

Actively cock blocking your wingman with the force of a 20 ton nuclear bomb. Not to be mistaken for regular cock blocking which is done passive aggressively. This form of cock blockage is done so effectively that you will never again see even a remote patch of feminine pubic hair in the presence of said cock blocker. Sometimes going as far to not get laid him self just so you don't get laid.
How is it possible that you are such a power cock-blocker that you made sure i didn't get laid on my own wedding night?

cock blocker spaniel

A domesticated member of the family canidae, not necessarily a cocker spaniel, which jumps up on the bed while two humans are engaging in heated intercourse. This usually occurs right as one is about to climax.

This unwelcome interruption completely ruins the moment. The offending dog, which may or may not be a cocker spaniel, is usually jolted off the bed by a quick kick, followed by an awkward resumption of intercourse.

Note: the dog must be a cocker spaniel.
Couple: *grunt grunt*
Dog: *leap*
Couple: fuk off u cock blocker spaniel
Dog: *sad howl*
