Drunkjury
An injury obtained while inebriated. Generally associated with binge drinking, Drunkjury's usually are obtained during a black out period and the source of the injury is often not remembered the next day.
Ya, you totally ate it in a wheel-chair at that party last night, we thought the wheelchair was safe for your drunk ass but somehow you managed to flip it over. Your arm id pretty messed up, sweet Drunkjury.
