According to a 1947 study titled Why Do We Smoke Cigarettes, smoking stimulates the "erotic sensitivity of the oral zone." That's exactly what you want to be doing.

There's two factors that will play to your advantage.

1.) Every girl needs a rebound guy, why not you?
2.) Her self-esteem is low, and she needs someone make her feel like she still has it.

Guys cheat on girls, and they need to even up the score. This is one of the few times that a girl is actually looking for some action.

They don't call it a bulls eye for nothing.

As best put by Seth from Superbad, "Ah man, I was so shit-faced last night, I shouldn't have f'd that guy?' We could be that mistake!"

If the skirt covers 1/3 her thigh, her midriff is showing, and boobs hanging out....that classifies as "Skank Attire"

Girls go out with their girlfriends to hang out. They have no intention of going home with you. Besides, you'll have at least one "mother" who will talk common sense into your target.

Girls want to hook up just as bad as guys do, but they have to worry about being judged. However, if they don't know anyone to judge them, they have one less thing to worry about.

If she's showing off, she's trying to get people's attention.

Girls don't go to bars by themselves without wanting to get picked up. Just make sure she's not hooking first.
