The prank starts out with a harmless message like this:
You're not though. Your friend is tricking you into snapping a flop picture of yourself:
Luckily, mine wasn't so bad. My friend, who was all ready for bed, faired differently, by her account.
With that said, if you haven't tried out the prank, go ahead! See what (potentially) embarrassing pictures you can get of your friends...and share them. Definitely feel free to share them.
