Splatty Mayonnaise

The resulting substance that usually sprays a man after he cums in a woman's ass and pulls out too fast causing her to fart.

Splatty mayonnaise went all over me after the girl I just did in the ass farted.

A buff fag who thinks he can play soccer and thinks he's cool because he can drive a car and has a girlfriend who is probably low key cheating on him.
