When you take someone, hang them from the ceiling (chandelier or something) and shoot bubbling champagne up their ass. The person will then involuntarily spray feces everywhere due to the pressure build up. Once they are shooting their person pudding, give 'em a spin and go muddin.
I got some poo in my eye last night when I did some muddin with my friends.

when someone takes their truck offroad and tries to get their car as dirty as possible. The idea is to get your car so dirty that the air-conditioning spits up dirt molecules when you turn it on. That how dirt you want it. WHen everything is said and done, your car must be totaled by running into a steamroller. Those are the rules
A few boys went muddin and totaled their car when they hit a steamroller.
