Muddy Napkin

An act of revenge: When seeing a person who has pissed you off or you otherwise don't like in a restaurant, you first must pose as a staff member of the establishment. Then take their napkin holder off of the table pretending to refill it. Then take the first napkin and wipe your ass with it. bring the holder back to the table and wait for your victim to hopefully wipe their mouth with it unsuspectingly.
