The girls (aka. bitches, whores, sluts, skanks, or young ladies) that are at the bottom of the food chain, and hence at the party during its last moments. The kind o girls that you seek only after your last resort has fallen through... the last resort of last resorts. The beatch you hit up before heading to McDs or home to pass out as an unsatisfied loser.
