gentlemens cockblock

When a guy has given permisson to another guy that he is aloud to cockblock him when he is talking to a fat,unattractive,slampig girl. Mainly happens when you are drunk.

-- At a Party --

Joe-Hey if I get really drunk tonight and start talking to a slampig can you gentlemens cockblock me?
Jesse-Sure!
-- 2 hours later really drunk --
Joe-You are so hot.
Slampig- aww come here!

*about to kiss*
Jesse-*Steps in between them pulls out Joe*
Joe-Thanks
