Cockblock

When you are attempting to get close to a girl and your buddy won't leave the room or starts telling less than flattering stories of you that cause you to lose an opportunity with your new female acquaintance.

Sara was sitting on the couch in the living room, Eric had been talking with her all evening, the party was over, Eric was attempting to get close to Sara but David wouldn't leave the living room even though he kept nodding off.

cockblock

To fully understand the ways of a clockblock, one must set a scenario. Ok, say you've been out all night hanging with this girl, and can sense that you are mere seconds away from going upstairs too hook up with her. Here comes your good buddy cockblock. His drunk, attention-needing self jumps right into the picture and tells your woman how beautiful she is, then throws up all over her. Instead of giving you a quality BJ, she drives old Cockblock home, leaving you by your lonesome to jerk off all night.

Male: You have really pretty eyes.
Female: Do you feel like going---
Lukas: I LOVE YOU!

Male:"Damn cockblock...."

cockblock

When your hand is down your girlfriend's panties and your mom walks in.

Got cockblocked by mom last night. Amy said she was ready to go all the way, but she went home instead and I got grounded. I might be a virgin for another week yet.

Cockblock

To interfere with a male's attempt at talking to a female or the other way around, especially if it involves sex. This is mainly performed by obstructing the path between the male and the female. Normally, the person that's doing the "cockblocking," has the intention on talking to the male/female.

BABY MAMA: I'm talking to this guy now name Terrence. He's a nice and comical guy.

BABY DADDY: You gonna have to cut that man off, I don't care if he's nice or not, he better not be in the picture.

BABY MAMA: Oh, now you wanna cockblock for the simple fact that I moved on without your sorry ass.
