Wedgie
A wedgie happens when a person's underwear is forcibly pulled up their buttocks. A wedgie can be given by bullies to humiliate their target, or as a prank between friends. Wedgies can be given from the front ("melvins") and in many other ways. They can cause the underwear to rip. They are very painful and are used in many situations. They are also very commonly shown in Low Comedy.
