The feeling caused by holding in a fart, that results in the poop being carbonated with the unpassed gas. The resulting poop is bubbly and airy, and often painful to excrete.
Man, I've been holding in so many farts that I'm getting fecal carbonation!
My asshole just got torn apart by my shit's fecal carbonation.
