Wedgie

When underwear is grabbed by the waistband and yanked up into the butt crack.

My dad and brother ganged up on me giving me a painful basketball shorts wedgie.

Atomic Wedgie

When someone's underwear is pulled up so high it goes over the victims head and over their eyes, and they are blind from the band being in their eyes and in males case ball pushed back.

Mark just got an atomic wedgie. That must hurt!
