A girl who has lost all sense of decorum and composure in a night club or bar. Spotted dancing on bars or VIP booths, projectile vomiting in the bathroom or back alley.
A 3 A.M. girl has Paris and Lindsay as their patron saints…their libation of choice is whatever they can afford or is purchased for them and they seem to develop an aversion to shoes somewhere around the 3 a.m. hour.

While usually seen at or around 3 a.m. (when the ugly lights come on in the club) there have been sightings as early as 9 p.m.
