Toasting with intertwined arms.... whats the meaning?
and if a girl initiates that with a guy, what's the meaning?
Just a wild guess. I am thinking that it has to do with showing unity (ie. tying the knot) Don't know if this is the true reason, but it makes sense to me. As for who initiates the act, I don't think it matters as long as both people are willing to show their unity.
it like something some people do when they get married, just to say we are together now...
it means you in this toast together
