If it's an actual "friend" and not an acquaintance, then they should respect the bro code, i.e. this guy brought this girl out, don't hit on her and make your buddy look good. If you're friend is maliciously undercutting you in front of girls, drop him.
I don't get how good friends fight over one girl to the extent of a friendship ending. There are plenty to go around.
