jessicas mountain 

The part of your pants or shorts around the crotch and zipper where excess zipper and fabric material fold outward forming a bulge, resembling a mountain, or even a boner; though both males and females are often victims of jessica's mountain. Jessica's mountain can usually be seen when one is sitting down.
