What becomes of an underclassmen when an upperclassmen takes an act or statement of an underclassmen and makes them severely regret it. In essence, the underclassmen was raped by the upperclassmen and has to walk around sporting their new butt tunnel until the swelling goes down.
If an underclassmen challenges an upperclassmen to anything and then looses his ass becomes a butt tunnel due to the rape he just endured.
