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.
