fredgie

n. A front wedgie; a combination of those two words; a wedgie in the front.

Fredgies usually result in the act of wearing too short or too tight shorts.

Typical teenage girl: its summer, its so freaking hot. I just cannot wear pants today.

*puts on shorts and hits the town

after some time walking around, her shorts have ridden up and bunched up, thus giving her an uncomfortable Fredgie.
