When you're about to score but someone ruins it for you.
Can be ruined for one or both parties.
Best described with an example.
Haley and her boyfriend Andrew were having phone sex when Andrew's brother James walked in.
Andrew: Then I'll take off your shirt and your bra and bite your neck and pull your hair
Haley: I'll take off your shirt and your pants and get on top of you and start biting your neck softly
Andrew: Then I'll move down to your stomach and take your panties off and I'll start to eat out your pussy
Haley: Next I'll take your boxers off and kiss your dick, I'll get on my knees and start sucking your cock
Andrew: Mmmmmm, Baby, what's next?
Haley: I think that's up to you;)
Andrew: I want you to suck me until I'm rock hard and about to explode. Then I'll get on top of you and pin you to the bed and start to put rock hard cock in your tight, wet....
James: Hey man, what's up?
Andrew: You fucking cock block!!!
James: Who are you talking to?
Andrew: Haley!!! We were having a good time!!
Haley: Tell you're brother he fucking ruined it!!!
James: YOU'RE WELCOME
Andrew: Get out James!!! Baby, I'm not horny anymore. I'm sorry my brother's a fucking cock block.
Haley: Ugh, neither am I. Tell him that I'm fucking pissed at him.

One who prevents another from scoring sexually.
Trudy and Dan frequently had time alone but her cockblocking roommate ruined any chances they had to have sex.
1.) To interfere with someone who is getting acquainted with, conversing with, or hooking up with a member of the opposite sex
2.) A motor vehicle maneuver, usually done by insecure twenty-something males (who think that everybody wants to race them) and other ignorant people, designed to prevent someone from changing lanes in traffic
1.) At the club, Sal was was about to get Lisa's phone number, when Nathan came up cock-blocked him by asking him if he found a job yet. He made it even worse when he reminded Sal that they had to hurry up and catch the last bus home. Lisa rolled her eyes and walked away.
2.) I realized that my exit was coming up so I began to change lanes, but that ricer cock-blocked me
3.) The traffic on the highway was hell, mostly because of that soccer mom driving the minivan in the far left lane, pacing and matching speeds with the semi in the middle lane. She cock-blocked us all.
(n.) one who prevents another from getting "play", "poontang", etc.
(v.) any action that impedes or stalls another's "game", "mack", or "pimp manuver"
(n.) I was dancing with this girl, when this cock-block stepped in between us and started grinding with her.
(v.) I had finally convinced Susan to go to my friend's keg party with me, when my Dad cock-blocked me by taking away my car keys.
When a friend or person prevents one from hooking up with a potentional mate. Usually done on purpose by a friend or person that will go to extreem lengths to prevent one from hooking up or getting some. Can be done by accedent, but usually not likely. Also know as cock blockers or cock blocking, these indeviduals of interception usually have the hater mentallity of, "Fuck that guy/girl!!, If I can't get it, they can't eather!!, or the famous I'm just going to fuck this up for this person because I'm a HATER!!! Also known as purpratrating hating, ass deflecting or scary ass. These Interceptive, bypassing, mercenaries must be stopped!!!
"I was macking on a girl and my so called friend was butting in on the conversation, then pointing out my flaws, then trying to bring up my old relationships, then bug-a-booed the girl all around, then tried to tell her to call him in a different language(they both spoke the same second language), Then followed us around the whole night(even falling asleep by us then wakeing up at the first sign of movement, jumping between us, making me drop her off first and we were entering his(the cock blocker's) drive way, not allowing me or her to exchange phone numbers, this all acts of true COCK BLOCKING, COCK BLOCK, COCK BLOCKED, COCK BLOCKER." true-Mon, July,14,03

If your a pedophile he is the definition of a cock block.
Something that keeps you from getting action.
That bitch scares all the other chicks away! She's a total cock block.
one who prevents the cock from being unleashed upon a woman.
I had a hot girl in the room, but Alex would not quit playing WoW and subsequently became a cock block.
Alex: "no, one more raid, there's a hot sorceress in here, i think she wants to get into my pixel pants."
