Stinky Poo Butt

The most degrading, shameful, demeaning insult a 5 year old could call you on a school playground

"A child called me a Stinky Poo Butt, and I've been crying for weeks"

The act of gas inside of your stomach being forced out by either a burp or a fart

Excreting gas from your ass

“Yo I just fucking farted, it stinks in here now!”
