fisure: a rip in the anal cavity during rough anal intercourse. Usually found after a large erect object enters a hole its to small for, or the hole wasn't properly stimulated and prepared enough for the large erect object thus ripping the skin in side the asshole.
Rebecca was in pain and had to visit a doctor due to her boyfriend's huge member ripping a fisure inside of her asshole.
