A waffle Burger is a complicated sexual act. To perform a Waffle Burger, firstly the man ties some fishing wire to a piece of bacon (or any kind of meat) and gets his woman to swallow it - making sure he is still holding the other end of the wire.
When the man is about to climax, he yanks the wire (still attatched to the bacon) causing the lady to gag. This gag reflex tightens her vagina and causes a more pleasurable orgasm for the man.
Waffle burger's are a common sexual act performed in the nearby English viallges, Alrewas, Yoxall, Kings Bromley and Barton
