A condition where during long anal intercourse, a person's anal tissues become so loose to where when the penis pulls out. The anal tissue pulls out as well. The result leaves a (somewhat) permanent bulge of tissue in the middle of the ass, resembling a ripely picked red tomato.
"My boyfriend spent so long fucking me in the ass last night, that I now have a 'red tomato' that will take weeks to heal!"
