Scandinavian Dipswerve
The Scandinavian Dipswerve is a method of dipping frites into any sauce by inserting the frite into the anal or vaginal opening, then swiveling your body to dip the frite into a cup of sauce held in someone else's hand.
My friend got so drunk he tried to pull a Scandinavian Dipswerve on a passing waiter with a tray full of sauces for another table.
