What does it mean when someone sits on their hands?

[Anonymous]

Was talking to my boss and he was next to me sitting on his hands.

Does he feel uneasy around me?

Usually, it’s just a phrase for doing nothing about something but for someone to actually be sitting on their hands, maybe it’s just comfortable to them

He's trying not to masterbate in front of you

His hands might have just felt cold.
