turkish camelback ride
The mother of all wedgies. Give someone a wedgie, lay them flat on their stomach, bend their leg back & hook their toes into the waistband of pulled-up underwear. Not only is this an ultrawedgie, but the only way out is for the 'victim' to pull their underwear even further up their butt to get it off over their toe.
Initiation to the track team was a Turkish Camelback Ride; except for Dave, who got a DOUBLE Turkish Camelback Ride; yup; both feet hook into his underwear.
