What does it mean when a girl swallows their lips inside their mouth (hiding their lips or pursing their lips) when looking to a boy?

Well when I'm arriving to parking lot of campus, I saw this girl with her motorbike going out of the area. We met each other on our motorbikes without stopping, she swallowed her lips while looking at me. We're not close to each other. We study in the same batch but in different classes. She's very beautiful. What does it mean? Does she like me?

I do that or lick my lips all the time. Purely out of habit, never with any sort of hidden agenda, though it does get awkward af if I happen to make eye contact with a guy at the same time.

It doesn't need to mean anything at all.

One time doesn't mean much, especially if you don't know her. Maybe she was thirsty! But if she does it over and over, it means she is nervous around you or thinking of something sweet to say.

Please stop saying "swallowing her lips"..

Now, it could mean she's nervous or that she is thinking hard about something...
Or possibly just licking her lips secretly lol

She could be trying not to smile, I do that when I'm holding my smile. But it depends on what situation it is. She could be thinking of something.
