A woman that rejects you before she knows anything about you.
That cock block jerkette just turned me down and she didn't know anything about me.
Any form of delay or douche-baggery resulting in either a check fire or end of mission. Usually employed by helicopters flying around knowing the gun target line and blatantly disregaurding it in order to try and steal a kill from artillery. This is done because frankly helocopters just aren't sneaky enough to get their own kills, and staff officers swing from air support nuts.
Fister 1: Shot tgt#1234, check fire we have helos on the gun target line.
...an hour later.
Fister 1: Cancel check fire, end of mission this shit took way too long and helos scared them away.
Fister 2: Dude we just got fire mission cock blocked!

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!"
An douche bag maneuver pulled off by Jay Leno through sucking network executive cock.
I used to think Jay Leno was an old, worthless sack of shit that has been on the air for far too many years and has overstayed his welcome onto my television, but ever since he pulled the prime time cock block on Conan O'Brien I just think he's a huge faggot.
CEO Steve Capus: I'm still not convinced. Get Jeff Zucker over here maybe ill change my mind.
Jay Leno: Yes Mr. President nyum nyum nyum.
