A gigantic, sometimes painful fart that explodes out of your asshole. This act will often be performed in the face of an unsuspecting victim.
I had taco bell last night and had the ass stomper of my life. I thought I ripped my asshole.
A person who enjoys fisting of the asshole but more importantly like to stomp, kick or punt the arsehole
It was weird when he told me he was an ass stomper... But I enjoyed it anyways
