Stinker wrinkle

The large flaps of skin surrounding the anus, which hold in the horrid smell of old salami and onions, until a person of obesity bends or squats in order to change underclothing. Hence releasing a horrible stench similar to a dirty gym bag. Causing the evacuation of said room.

Everything was okay, until she was about to climb into bed and revealed the scent of her Stinker Wrinkle!
