facetech
Facetech is a primitive method to communicate without SMS, VoIP, email or IM, in other words, just using verbal/sign face-to-face language. This method of communication is sometimes avoided as there's no logging of conversation so nothing to go back to on Monday morning when everything has been forgotten.
