When you don't answer your cell phone for a couple days because you are sick of having to talk to people, and all your friends think you are dead, but you really just needed a break from it all
Jane: Where were you last weekend John? I called you a million times and you never answered or returned my call, everyone thought you were dead!?!
John: Yeah..I was phone dead last weekend, I just couldn't take it anymore, but I'm back baby!!
