Etymology: "Zonking" is the form of "zonk", which first appears in print around 1950, and its origin is unknown. Dictionaries generally treat it as imitative, a sound made to match an action or feeling, much like "bonk" or "thunk". The word seems to have been built to suggest a dull, heavy blow, and that heaviness is what carried over into talk of exhaustion. The sense of being knocked out or dazed by something came first, and the drowsy, fatigued sense grew out of it. Someone who is zonked has been struck down, not merely sleepy. That is why the word fits fatigue so well: it describes weight and impact rather than a gentle slide into sleep.
