This is based on Nepali Context only, (not americanized yet).

Generally when a boy friend (keta sathi) marries and both of his friends (keta and keti) call his wife as 'bhauju'. This situation is not so hard but when it comes to keti sathi's husband, how do you call him? For girls most of them say as vinaju but how about guys? If he is in your age and already introduced to you, name may be enough. But if he is little aged than and you have to show sorta respect, how do you call him? calling him as 'jwai' or 'vinaju' is definitely embarassing.

I came through this situation couple of times and I could not determine, what's your logic?
