Wedgie

A wedgie is the practice of pulling someone's underwear up causing the underwear to wedge between the buttocks. It can be inflicted as a practical joke, or as a form of bullying, depending on the context and people involved, and can often be painful to receive. A wedgie can also happen when a person's undergarments get bunched up and "ride up" between the buttocks, causing discomfort and annoyance. This can be caused by bad posture, awkward sitting or tight underpants.

In 2007, eight year old Jared and Justin Serovich came up with "wedgie-proof" underwear at the Central Ohio Invention Competition 2007 where their invention got them into the finals.
