mud butt is when you eat sumthing that dont agree wtih you. then maybe an hour later u get cramps in ur ribs and u start to fart every 2 minutes. then ur stomach hurts and every fart is wet and hot, and sonner or later it isnt safe 2 fart, u need to shit. the moment u pop a squat on the throne, ur butthole opens up and it runs right out....and the smell is horrible!
