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.

Mattsplaining 

When your friend Matt has a compulsion to explain why things are the way they are, even though they are dumb.

"Why can't I order from an Ontario restaurant through UberEats in Gatineau even though the cities are only divided by a canal ?? This is dumb."

Matt - " Actually because Hull is technically in another province and Ontario and Quebec have different health standards, and it's not dumb because health standards are important and allowing one province to dictate another province's health standards is even more irresponsible. Order from the website."

"Matt...you are mattsplaining again."
