So, been doing a lot of partying recently and meeting lots of people both guys and girls. Met a girl at the last big one, we danced, smoothest I've ever been. Today I was bored so I typed her name in on FB. She was the first thing that popped up even though she's like 40 miles across in another state. She has an uncommon name so it makes sense though.

Should I add her?

She was tipsy the night, she was dancing with a few guys, my friend included, but I believe only I was actually making out with her (Though the guy she was with than tells me she's a ho and sucks a lot of guys off. He might have been her friend but she was dancing on him too). I noticed she was hanging around where my friend and I were hanging around and would scratch my back to get my attention a lot when I was in the area to dance wit her. Why I want to add her? I might have a possible hookup, maybe LTR, I expand my social network, etc. Why shouldn't I? Probably creepy, might spoil future run ins with her...though I may never even see her at these events, might throw me in a bad habit of adding every girl I meet..

New info:

Looking at her FB Profile, she seems like one of those girls that posts a lot of 'relationship' type stuff. Like "My dream boy" or lots of pictures of hand holding. Just to give some idea

I wouldn't add her... Its needy. If she was into you as you say and didn't add you already... Maybe it was completely normal for her to hook up with you and it wasn't a big deal. Kissing ain't that deep nowadays, that much I've learned.
And judging by the info you provided about her profile she seems like an attention whore, and she most likely IS expecting you to add her.

I say just move on.

I didn't ask her to add me, or for a number, just told her my name like normal when we met

personally i would just add her. fuck it its the only way of contact you have. Add her but dont initiate conversation ! if she was tipsy she may have forgotten your second name or what not.

do it ! if she initiates game on if not maybe like one of her posts or whatever !

What are the odds you're going to run into this girl again?

Have you run into her before?

If FB is going to be your only way to communicate (like you don't think you'll see her around most likely) - listen to Stenic - that's my opinion...

Nothing to lose.
