When a male or female has an attractive face from the side, but when viewed from the front their face is thin and unattractive, as if someone has squashed their face inwards (much like a compressed accordion ). An inverse would be a face that is fine from the side, but is wide and unattractive when viewed from the front (much like an outstretched accordion).

Human #2: What?
Human #1: You have one hell of an accordion face.
Human #2: Dick.
