pinching george

When you have to take a major dump after a meal, such as Taco Bell, but the time is not now, so you pretend as if there is an imaginary quarter up your asshole and you have to clench it there.

“Hey Mikey, are we almost home? I’m about to piss myself!”
“Bitch I’m getting bathroom first! I’ve been pinching George for the last 20 minutes!”
