stealfie
When you take a selfie, in order to get a pic of the person/situation behind you...
I had to take a stealfie in front of the crazy-but-kinda-hot crossfit chick, because if I took a picture of her, she would probably kick my ass... or talk to me about crossfit.

Stealthily taking a selfie so people around you don't know you're dumb enough to be taking a selfie.
My girlfriend asked to see what I was wearing to work, so I snuck a stealfie to send to her. I looked like I was stretching to draw the eyes away from my phone.
