What does it mean when guys tap their fingers?

[Catty_Turner]

I decided to let go of a crush since he hasn't been showing any signs he likes me, but today when I kept glancing over at him after a while he started to tap his fingers (like rolling all four of them) pretty fast. Does this have any meaning to it?

what like pinky to index, and back? I do that when I'm bored. It's just something to occupy myself.

I tap my fingers in a beat if I 'm bored too.

And then some guys are just jittery xD

No. I do that all the time and it just means I am having an ADD moment

I doubt it. He probably is just having a hard time holding still.
