One who very much much enjoys tricking his
friends, and dragging them to
random bars, to ultimately end up at a bar where his girlfriend "coincidently" happens to be at; ultimately causing his friend to catch a cab home alone- all so he can
eat his girlfriend's cake. Thus, the cake eater.
Scott: "Hey, this bar sucks (when
really it doesn't), I know a much
better bar, follow me. Oh, wow, what a coincidence that my girlfriend is here!!"
Me: "You are a cake
eater."
