A distinctly disgusting odor emitting from the junk of lazy and/or European dudes who are probably not circumcised or the snatch of dirty street-walking skanks who require a drip pan between their legs. Often identified by the large mass of flying insects buzzing around the crotch of said male or female. At it's worst, crotch rot can include the oozing/dripping of a greenish, highly toxic liquid.
A stomach-turning but highly effective form of birth control.
