self cock block

Self-inflicted cock block by doing or saying something so stupid, cheesy, or inappropriate that you instantly ruin any chance of scoring with the targeted girl. The girl will inevitably laugh at you later with her friends

I self cock blocked myself yesterday by telling a girl if she was a new sandwich at McDonald's she would be called McGorgeous. She spewed her drink in my face.

Cock-block 

Anyone or anything that gets in the way of you getting some. The cock-block can be male,female, or inanimate. Many cock-blocks can't get any themselves so they try to stop somebody else. If they ain't scorin' nobody's scorin'. No scene is too embarassing in their undying quest to prevent your action. If your buddy's a cockblock don't bring him or her.

1. My old boss, Bob is such a cock-block. He won't let any of us guys chat with the female employees.

2. My car was a cock-block. It broke down on my way to the party so I couldn't go and possibly hook-up. I had to wait for the tow-truck to come and tow me home.
