cock-blocking 

When a friend of yours calls you while you are about to get it on, or when someone comes in while you and your partner are about to have intercourse and keeps you from it by talking, making noise, etc.

Dude, don't call me. Stop cock-blocking!

cock-blocking freshman fuck 

a squitchy little horrible freshman kid that comes up to you while you're making out with your girlfriend and says, "NO PDA!" because he is sexually frustrated and thinks he's being clever. this is especially frustrating when you're trying to cop a feel.

cock-blocking freshman fucks often congregate in groups. these obnoxious and useless creatures are often found in ideal makeout locales such as stairwells, smoking patios, and dark abandoned corners, but only after you've started making out do they choose to reveal themselves.

cock-blocking freshman fucks should be forced to wear muzzles.

tease: "oh, no...i shouldn't..."
horny jackass: "come on, baby, just one feel."
tease: "...oh, fine."
cock-blocking freshman fuck: *leaps out from behind garbage can* "NO MAKING OUT IN SCHOOL!"
horny jackass: "you little cock-blocking freshman fuck!"

cock-blocked

1. when a guy who is interacting with a cute girl hoping to get ahead sexually is blocked from taking it farther by someone or something

2. either devine intervention, karma or poor luck preventing a guy from getting laid or succeeding sexual with a girl.

3. when a friend of either the guy or girl prevents the two from hooking up

I can't believe you just fucking cock-blocked me you prick, your like a cock-blocking dog that just pops up a the worst moment to fucking kill someones chance's of fucking scoring!

Cock blocking is not always a bad thing. Sometimes it is necessary to keep a friend from getting ass that he wouldn't normally go for, but he is to fucked up to know better.

Ben was so fucked up that he was trying to get with a fat ugly bitch, so we cock blocked him to keep him out of the nasty.
