1 is hiding a knife and is ready to stab you.
2's shirt saying "certified perv" along with having a nose ring indicates there's a 100% chance she's down for butt sects.
3 is possibly hiding a Mr. Winkie that she'll use on you once you're passed out drunk.
So....2, 1, and if 3 isn't packing she jumps to second place behind the certified perv.
