Plumber-Butt Syndrome

Whenever you see a man or woman, (typically a man in his round weight probably like 200's), who deny too wear belts in public, their pants ever so gently slip down to reveal their ass crack. This is commonly referred to plumbers, who have it happen naturally whilst working on pipes. Its a mystery how their booties keep escaping the fiber confinement that is jeans.

Man 2: "Nah, i was starin at ya ass, i think you got plumber-butt syndrome. You really gotta buy a belt."
Man 1: "Maybe i gotta buy you a pair of glasses."
