Girls, does it mean anything when you bat your eyelashes at a guy?

Me and this girl have been talking a lot lately and she seems to like talking to me. Today we were with some friends and I was talking to one of them and she was there too. My friend and I were discussing movies and I usually have no problem swearing but she was there, so I refrained from saying the "f" word and I turned and told her I couldn't bring myself to swear in front of a lady.

My friend then said "oh, look how nice he is, isn't he an angel?" And this girl put her hands under her chin and started smiling and batting her eyelashes at me. She looked really cute doing that and I wonder if there's any meaning behind it. I mean , I've seen her around other people and she laughs and everything but she doesn't do anything like this and people feel awkward because when me and her are in the room, its like we ignore everybody else and just focus on each other (at least I feel that way because we are ALWAYS talking) do you think it means anything?
