when you pants someone, and their underwear/boxers gets pulled down. usually happens because underwear/boxer is very lose and baggy.

or can happen when you pants someone who's going commando at the moment.
Joe commando pantsed Jake by accident. Jake shouldn't have have worn such baggy boxers. commando pantsing can be very unexpected and dangerously embarrassing.
