Selfie Target

When someone is watching you, then poses for a selfie, back to you. The angle they're shooting from would place you directly in frame behind them. The area is otherwise empty, with far better backdrops. You, my friend, are a Selfie Target. This individual will likely upload to social media to poke fun.

I saw what she was up to, then shot two middle fingers to her phone camera. She turned around, expression of getting caught. "That's right, B*TCH! Don't Selfie Target me!"
