Gag in a Bag
A gag bag is when you stick your whole nutsack in someone’s mouth and make them choke on it. It’s either a sexy move or a prank that wakes people up screaming.
I stuck my nutsack in my friend’s mouth and he choked on it.
My girlfriend did that to me during a sleepover.
He fell asleep with his mouth open and I stuck my nutsack in it.
