The orthographic interpretation of a mumble uttered in place of a person's name during a sudden lapse of memory. Usually occurs when a person enthusiastically bids farewell to a friend and abruptly pauses mid-phrase to recall the name, emitting this onomatopoeia instead. Oftentimes will be accompanied with a hand over the mouth to distort and muffle the sound panicked facial expression.
