Why would a man wear a thumb ring, what does it mean?

[Anonymous]

So there’s this man I really fancy and I looked at his hand today and he has this big silver plain ring on his thumb I’m pretty sure he had on both thumbs? I’ve never seen him have this before. What does it mean?

I had a phase in my early 20s where I wore a platinum thumb ring along with having a silver pinkie ring and a silver lighter, and all rather expensive. I don't know why I liked these things. I just liked the style back then combined with black shirts and things of this sort. It sorta matched the tat for me. I've heard some people suggest it might be a statement about sexual orientation but I was heterosexual. Maybe my fashion taste was a bit strange back then but I just liked how it looked.

I don't know but for some reason picturing that makes me really uncomfortable...

It means he is in the band nickleback.
