When a bro cock-blocks a friend who has is running game on a girl that he should not be running game on, or will regret hooking up with.
Cy - "Brad, I can't believe you were such a cock-block last night!"

Brad - "Are you serious, Cy? You did not want to get with that, she had a fupa! I was just playing brofence!"

Cy - "Thanks, Bronamath, bring it in for a brojob."
