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...."
