A bag full of motherfuckers
A bag made of strong fabric, like burlap or denim, filled with at least 3 motherfuckers, all tied up like criminals.
He pulled out the bag and 3 motherfuckers fell out and started yelling at him.
The bag looked like it had been thrown in a lake and pulled out by a motherfucker.
She opened the bag and a motherfucker jumped out and bit her arm.
