The condition of extreme lack of good judgment that sets in usually after 11 pm and often on a Friday night after working a 12 hour shift and then staying up all night partying or gaming with no regard to your body's extreme physical demand for sleep.
Often characterized by waking up
the next day and only having vague recollections of what extremely dirty things you said, did, or items of clothing you took off the night before.
Evidence of recent midnight madness includes an empty 12 pack of Mt. Dew (or an empty 5th), car parked sideways
on the lawn, finding someone else's keys in your panties....and the
inevitable awkward feeling when you catch your friends or your boss looking at you sideways.
