An insecure asshole who does not have the balls to open a conversation with a woman, but will not hesitate to butt into any interaction already in progress. They will then proceed in destroying any chance of a hook-up. Most times, what they refer to as "their game" is so poor that not only do they fuck up YOUR prospects they end up scaring away the "prey" to another table or "Lance Goodthrust" at the other end of the bar. They are the most effective birth control device known to mankind. Stay away from these people or become a monk where you'll have just as much opportunity for getting some pussy.
You're talking to a hottie that you've managed to cut away from her heard. You're just about to "close the deal" with a number or invite to a more secluded place ie. your car, when "CB" shows up and hangs over you both like a plague from God or bad breath or herpes. The conversation, which had been flowing with magical bullshit, becomes strained and uncomfortable. She mentions that "it's getting late" as she eyes the safety of the heard. Her departure is followed by, "She was a bitch anyway!" from the asshole who's just ruined it for you. You supress the urge to punch him in the liver, move to another part of the bar where you start again in the hopes that he cannot find you. For surely he is the Devil.

definition: a c-blocker is a guy that will do anything in his power to make sure you don't take home a girl.
At a house party; When you tell the girl "its kinda cold outside wanna go up to my room", he will sping into action and give her his jacket.
At a bar; you will be in the zone with a girl and she's clearly into you, all you have to say is "wanna head back my place" and it would be a done deal, thats when a c-blocker goes in for the kill, he will walk up to the bar between you and her and say "hey can i buy you a drink",
c-blockers can even be your best friend; you can tell your buddies how much you like this girl and they will tell you to go for her, but every time she is around your c-blocker friend will hit on her or make sure he takes the seat next to her where ever you go together, often he will get ahold of her phone number and invite her places without you. when you ask him what the deal is and why is he all over her all the time? he will say "what, she's my friend too and i don't even like her in that way, your acting paranoid".
often a c-blocker will never succeed in landing the girl, his job is to make it impossible for you to get her.
mike, brody, and james are the most common names of c-blockers so watch out you could be next!!!
friend 1: What happend with you and the girl last night at the party?

friend 2: i didnt that guy was just a c-blocker making up stuff so she wouldn't go home with me. after that she thought i had some S.T.D. and would not even talk to me

"It’s no wonder that many tattooists themselves refer to them as 'job blockers'. How can you take seriously anyone who has a fire-breathing winged serpent / the names of their three kids in sanskrit / the logo of a football team encircling their neck?" - WalesOnline Jan 13, 2009
