When you’re trying to hold a fart in, but it accidentally seeps out. When your bum hole gets hot and not knowing if its from sweat or trump heat- you finger it. Upon smelling your finger, and the end of your nose is covered in liquid cack: this is fart snot
Example: “oh shit Susan; I just farted and it felt wet”. *checks bumhole and smells*

Mucusy poo all over top lip - “oh Susan that’s definitely fart snot!”
