A phrase that originated from the 4chan /x/ boards. Often posted after creepypastas.
"A guy is at his house, making out with his girlfriend, when suddenly the phone rings. He answers it and a voice says 'TOUCH MY DAUGHTER AGAIN AND I'LL KILL YOU', and then the line goes dead. The guy asks his girlfriend about it and she says 'My dad's been dead for 10 years..'"
BUT WHO WAS PHONE?!
