Where a person's stomach has become so fat, and their stomach skin so loose, that their stomach hangs down so as to cover their genitals. This can happen to both men and women.
My buddy's awning is so huge that he can walk around naked in public and no one can see his penis.
Exceptionally long labia. Awnings hang over windows, thus the correlation.
Once I saw her awning I didn't want to fuck her anymore.
