A Surprise Gary is a move performed during sex when a guy pulls out to try and cum on a girl, but awkwardly fires in a wayward direction while making a creepy face. This typically happens too early, and leaves the girl unsatisfied and disinterested in a second encounter.
"Man, I feel like such a Creeper because I gave Jill a Surprise Gary last week. I keep texting her, but she won't text me back."
