When someone hangs you on a hook or pole by the underwear, forcing your underwear up your crack.
In sixth grade, I tripped on the floor in the hallway. I was late for class so I was the only one in the hall. I was lifted of the ground by my tighty whities by an eigth grader they dragged me by my undies to the flagpole, where he took off my clothes except my underwear and gave me a hanging wedgie. Everyone laughed when they saw me. The buses left and it took three hours for a techer to find me and get me down. It hurt so bad, because the undies were up so far.
