I don't see how this chic isn't fair game at this point. If you are worried about your boy just give him a heads up on whats about to go down. If he is really your boy, and see that you would be happy with ole girl, he wouldn't trip, he is the one that gave her away. What does it matter if its you or any other nikka after him, bytch isn't going to stay single. If this is truly a good girl, which is becoming harder and harder to come by, and you let her get away, you'll regret that shyt for a lifetime all behind some made up ass bro code.
