Fartpedo 

Being 100% confident with yourself that you need to fart, so you push as hard as you can to do the best fart possible. But instead of farting, you shoot shit at a fast speed directly into ones underwear.

"May I please be excused From the dinner table"

"Yeah sure Aunty Tayla, are you alright?"

"Yeah but I just Fartpedoed and need to clean this creamy behemoth out of my pants"

Fartedo 

A piece of feces that is expelled from the anus when passing gas.

I had to change my underwear after a huge fartedo in biology class today.
