no, like a fake one

The other day, I was chilling with one of my co-teachers in the technology lab. I was on a prep period doing work from a computer as she was doing work on her computer while watching a kid who's behavior had been out of control. She started playing some music and singing along to it. Justin Bieber came on, and in irony, she started belting it out. The student turns to her and says, "Wow, so you're like one of those for real white people." Without missing a beat, my co-teacher says, "As opposed to what?"
