A girl will put her macbook case on
upside down as a sign of being dtf. The apple
on the case will face the opposite direction of the
apple that lights up so that the two look like they're 69-ing. Bitch be horny.
Guy: Dude, do you think she's in to me?
Friend: Yeah, man. She's got an
upside down macbook case on her laptop. Totally dtf. Go mack, bro.
Guy: I
think you mean mac!
