1. An outgrowth of the BDSM safeword, by which you arrange with a friend before meeting someone new that you'll call him/her at a certain time. If your friend receives this call, all is well. If your friend does NOT receive this call, it is the friend's sworn duty to call the police and report a problem. Very popular in a world where you meet someone from the internet who might be crazy.

2. A friend you can call when you want to evoid someone else. You can literally call and start a conversation mid-stream, and your friend knows what you're doing and plays along.
1. Herbert, you'll have to uncuff me so I can make my safe call.

2. It may sound weird when Susan's on the phone, but that's because I'm her safe call.
