Catastrofist
A fisting session resulting in potentially life threatening damage such as rectal or large intestine perforation, hemorrhage, severe anal tears, or other internal organ damage.
The guy was moaning with pleasure while getting fisted by a guy who was 6 feet 8 inches tall, but when the fister's arm went into his ass past the elbow, the result was a catastrofist. His rectum and colon were perforated, his liver and kidneys were bruised, and he almost bled out as blood poured out of his asshole. Responding paramedics commented, "Oh my God! Get the emergency butt plug and a fistful of tampons, stat! I don't want to lose another dude to a catastrofist!"
