A wedgie occurs when a person's underwear or other garments are wedged between the buttocks. While a wedgie can be created naturally, the term is usually associated with a prank. When a person is on the receiving end of a wedgie, his or her underwear is forcibly pulled up by a second person.
Wedgies are commonly featured in popular works, either as a form of low comedy or as a behaviour representative of bullying. In such works, briefs are usually the type of underpants that are worn by the victim.

Watch out for these guys, they cruise by pretty fast on the Gandy, and can kick up some dust too.

Enjoy the outdoors!!
