The act of continuous eating at a pace where there is a constant supply of food throughout the entire digestive system. This produces a conveyor belt like effect where food constaly enters the mouth, and shit constantly leaves the anus in a seemingly endless stream. This feat is very difficult to pull off and is only attempted by the bravest of souls.
Whoa he's doing the shitveyor belt! Theres an endless supply of shit coming out of his ass!!
