What do you think about people that go around calling everyone "friend" and "buddy"?

I don't know I find it weird personally even tho I know it's common (for some reason) for people outside of American culture to call people "friend". I think it's just one of those weird things nobody ever talks about or mentions for some reason and just accepts/normalizes while not really thinking about it. It just comes off as being overly fake nice and trying too hard to "connect". I understand if it's an actual friend or "buddy" (even tho calling someone that is still lame to me) but you regularly see complete strangers doing this.
