Matt Splat

When you cum on a girl's stomach and she pushes the cum down in her vagina and uses it as lube much to your surprise, disgust, and slight sexual curiosity.

Amy is such a freak she tried to give herself a Matt Splat much to my amazement and secret arousal.

Matt splat

A some what portly old bastard. Often found smoking cigarettes and telling dirty jokes at the shop. He sells ice cream out a panel van.

Matt splat is a dirty old man.
