1. An extremely white guy that eats mayonnaise and ham sandwiches on white bread, wears long white tube socks with shorts and sandals, and is WAY too open emotionally and about sex (or the lack thereof). Usually college educated but completely oblivious to how anything in reality works. Has it made because his family is filthy rich and connected out the ass.

2. A ho.
Damn, Dave is such a mayonnaise muncher. His dad got him a job at a law firm after we graduated, and I'm stuck working at Mickey D's!

You're going out with Vanessa?! Don't you know she's a mayonnaise muncher?
