I met this really cute girl today, what should I do?

Okay so I was in a neighboring town today (it's probably an hour and a half away and I go there often), and I was at the mall when I saw one of my best friends from camp. He introduced me to this really cute girl, his best friend, and it wasn't instant attraction, but as the day went on I started to really like her. I found out a lot about her though. She isn't a virgin (she's 15, I'm 16 and still have my v-card). But it seems like she kinda likes me. We really hit it off, IMO. When she was leaving, we hugged for like 30 seconds (or what seemed like 30 seconds), and it's cheesy to say, but that hug was fucking angelic, I shit you not, motherfucker. When she started to walk away, I said, "I'll Facebook stalk you," to which she replied, "That's wierd," with a smile on her face... I couldn't tell what kind of smile it was lol. I never found out her last name, but with the power of Facebook and picture tagging, I found her profile... So what should I do? I don't want to seem like a creeper or anything and ruin my chances because she's really fucking amazing. Should I add her, should I not? What do I do?
The Facebook stalking part, I said that jokingly... Probably should've said that to her too... Fuck, I'm a dumbass.

Why would you say you'll Facebook stalk her. What a dumbass move. She probably only smiled to spare your feelings. You better hope she didn't take that comment too seriously.

Don't add her. Wait for her to add you.

Whatever you do, surely don't go crazy with your feelings for her and get on yahoo answers asking what to do....
