picking a wedgie
The act of pulling your underwear back into a comfortable position after a wedgie. The wedgie is usually a natural occurrence that happens to both men and women rather than from a bully. Such act is socially unacceptable and should be done in private (like in a bathroom) unless you’re good at hiding it.
Joe: Hey dude don’t you just hate it when your underwear makes your crotch uncomfortable?
Bob: Yeah. Picking a wedgie in public can be very hard.
