Bi-Girl

You: Hey guys, real quick, I need to ask an opinion. Can a straight guy date a bi girl?
Girls: Blah Blah Blah.
You: Hmm…well it goes a bit deeper, you see my buddy Phil has been dating this girl and yes it turns out she’s bi. It was no big deal until he realized that they share a former ex. So essentially he’s dating his ex-girlfriend’s, ex-girlfriend. What do you think about that?
