Is constantly rubbing one's hands together a nervous tic?

Is constantly rubbing one's hands together a nervous tic? I notice that when I'm with this guy he'd get very fidgety, at times he would just play with his fingers and other times, when he seems more on edge, he would start rubbing his hands together like excessively. And it's not because of the weather. We're indoors then.

When he was talking to me the other day, he was looking at my lips and then back at my eyes and repeating that for a few times. We were seated next to each other and he'd turn his head to look at my side profile when I'm sorta looking away (but hey peripheral vision). I knew he was looking and didn't wanna 'catch' him so I turned back really slowly and acted unaware.
Yes that is him being nervous around you
No rubbing hands is not a nervous tic
