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.
As soon as I got him to put on one of those $500 shirt, his girlfriend totally cock blocked me. What a bitch.

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.

Paul is a total cock blocker. That guy is like a giant cock blocking robot developed in a secret fucking government lab. I was about to hook up with Lily and he ruined all my hard work.

A hot girl's ugly friend who has a chip on their shoulder about no one hitting on them, so they do everything in their power to stop their friend being nailed. also the friend might not want to leave them alone. female cock blockers can however be countered by "taking one for the team" this activity involves your friend drawing a short straw and having to go off with the cock blocker so that your path is clear
"damn, this bitch is cock blocking me at every turn, tim can you take one for the team?"
"I'll take down that cock blocker, now run free unhindered my freind, go deep!"
"I'll take down that cock blocker, now run free unhindered my freind, go deep!"

Someone who tries to interrupt you while you and someone are engaging in some sort of sexual activity, usually with something totally meaningless or pointless.

Flatmate:"Wanna cuppa"?
Me:"Fuck off and leave me alone you cock blocker".
