According to this AP article, a high school wrestling coach has been reprimanded by the State of Oregon for biting a student. Yes, biting. He left "distinctive teethmarks" according to the article. Why would a coach/teacher bite a student, you ask? Well, it seems the wrestling team was attempting to give him a wedgie. Yes, a wedgie. In case you have been hiding under a rock for the past century, please see the following description as described on Wikipedia.
The Wedgie is a joke maneuver or prank performed to humiliate someone. It is inflicted when an individual, or group of individuals, grab the underwear of the victim from behind and pull up, causing the underwear to wedge between the buttocks. A wedgie is also what happens 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. (On the other hand, thongs are, essentially, designed to be wedged between the buttock. However, a wedgie while wearing a thong is extremely difficult to rectify, due to the garment's slender nature)
What is the appropriate defensive tactic when being attacked by a mob of high school kids intent on giving you a wedgie, anyway? I can't say I blame the guy, but also understand the State can't really condone the behavior.
Those of us who remember the show "Salute Your Shorts" on Nickelodeon know that a wedgie is not nearly as bad as a "Melvin."
