And she was single and really hot and I got to dance with her and feel her ass

. Then she went to take her drunk little sister home and I couldn't find her again. I got her phone number from a random guy after I decided to stop looking for her (a half hour after she left), and I found out she lives on campus (like I do).
So my question is: do I call her tomorrow (or ever)? If I don't, I probably won't see her again until the end of January because I've never seen her around campus before and I don't know what classes she has. If I do, she'll either a) think it's weird that someone she met for half an hour when we were drunk is calling her or b) give me a shot and go out with me.
Thought? Jokes and serious opinions are both welcome.
