指

[m_]

I'm really curious and would like to know why the small finger 指 means boyfriend/girlfriend in Japanese?

It doesn't mean boyfriend.

there is a link on the name of fingers here.




(I still haven't figured out how to link to halfway a page ^_^)

The small finger (pinky is it?) when shown to a man relates to a girlfriend or woman one is playing with.

Contrary, the thumb when shown to a woman relates to a man.
