<human>: Can you give me a shortened version of the text?

I'm in college, and well first of all, I have no experience with girls. I've never had a girlfriend, and I've never even been on a date with a girl, so I don't really know how to go about the situation I'm in.

I like a girl. She started out as a friend of a friend, but now she's more of an acquaintance (we don't really see each other that often, so I don't think I'm "friendzoned." But we do bump into each other occasionally). We've spent some time alone, however, it was just as friends. I don't really know how to flirt. I also don't know what's appropriate or not. Since I never really did this in high school, I don't know what's appropriate in college. For example, my friend initially suggested telling our mutual friend about it, and finding out if the girl likes me through our friend. But I said that sounded too high school-ish. So I don't really know how I should go about this.

I've tried asking her to have lunch together, but her friends have been there (however, I have spent time alone with her).

I feel like I am at the stage of officially asking her out, but I'm not sure. I haven't flirted with her at all, is that bad? How do I ask her out? Do I just say "do you want to go out sometime?" the next time I bump into her? Also, finals and winter break are approaching. Should I wait until break is over until I do this?
<bot>: in college and like a girl, but I'm forever alone, so I have no experience. How do I ask her out?
