FaceBook safety
Calling 'FaceBook safety' is like giving everyone a warning that you're not going to let them mess with your FaceBook anymore.
I called FaceBook safety before my brother started posting my face in a unicorn costume.
My teacher called FaceBook safety before I started playing games on my phone.
I called FaceBook safety at work because my boss was trying to post my face in a fishbowl again.
