A device that is used when people need to go to the toilet either for a shit or a piss and u dont let them, u take the tatey masher and stab their belly causing them to do their business there and then.
Great Party Trick :D
Someone tells u they need the toliet, u ascort them to the tatey masher torture tool and stab them unexpectedly!
