The Wheatland Stomp is a solo sexual act performed by only the most experienced of anal accepters. The act involves defecation on the floor by the actor, then stepping into the faeces. Then, the actor places his foot inside of his rectum and continually "stomps" inside of himself, stimulating the prostate and putting the shit back where it came from.
