When you're about to have sex with a girl but right before you penetrate, a guy (male) cuts in front of you and takes it up the butt, literally, booty blocking you.
Will: Man I was so close to banging this girl last night.
John: What happened?
Will: Well as you know, Ross and his gay ass was over, and well, he booty blocked me.
