The male definition of cockblocker is to sabatoge another guys chance of scoring with a chick. This concept was foreign to me until going out on occasion with my college roommates friends.

While one guy was is the bathroom, another guy would tell whatever girl was there things like... its a shame he has been unemployed for 3 years..... rough deal with that restraining order.... he doesn't pay his child support for his 4 kids........he is changing his colostomy bag...it wasn't his fault he caught herpes..... Stuff to that effect.. The girls wouldn't say anything when the guy comes out of the bathroom, the guy of course doesn't score.. then they never even tell the guy that was in the bathroom what they said to the girls.....

Shit is reprehensible..
Steve was a cockblocker when he told the bartender Paul was out on parole when he was in the shitter

1. One who socially gets between one or more potential couples. 2. A male who prevents another from getting laid by socially getting in the way.
1. I was right about to ask for her number, and then your cockblocking ass had to tell your stupid drunk story.

2. I was about to take her home, and then you had to make the remark about the old cheeseburger under the seat in my car, you damn cockblocker!

Opposite of a Wingman. A person who deliberately gets in your way of scoring in attempt of them getting laid by the same lady you are going for. A player hater who won't let you get back on third base by blocking and gets you out of the game. somemone who has less of a chance of getting laid by the same lady and still decides to block you from getting laid as well.
In a room are two people engaging foreplay and the cockblocker walks in the room and physically gets inbetween the two partners preventing them from further foreplay/intercourse. I got cockblocked! partly due to hating on a player.
