A term used to discribe a friend, preferably someone whom you know well so that when you call them they won't get mad, and usually an adjective is added before it. Originated from a bunch of emo-kids from California studying in Japan.
Grace and Lisa are friends, and Grace calls Lisa "face" because it rhymes with Grace, and after that everyone's name ends with the word face. For example, Gay-face, Emo-Face, Pussy-face etc etc
