A sexual action between two females:
One female goes and fills her stomach up with males cum, then pukes the cum collected all over the other female.
This is Blue Cheesing and can only be between two females.
Sharpe Cheddar is this action between new males.
My family walked in on my girlfriend Blue Cheeseing my chest. It didn't turn out that well, and my surprise birthday party was canceled. Thats when they learned I was gay.
Dude why don't you go whore your self around so we can get some sharp cheddar in before the game?!
