Expect nothing and you will never be disappointed. Expect something and the risk is you’ll be disappointed. If you know that feeling, then you should know the expression ryutodabi, an idiom that describes anticlimactic events and situations.
Meaning: an anticlimax, a strong beginning and weak ending, going up like a rocket and coming down like a stick.
Literal translation and kanji breakdown: 龍頭 (Ryutou; dragon head) and 蛇尾 (snake tail) form a disturbing image of a massive dragon’s head paired with a tiny snake body.
Ryutodabi: The Origins
Ryutodabi first makes its appearance in the Blue Cliff Record, or Biyan Lu, a collection of Buddhist koans compiled in China during the Song Dynasty (960-1279). The specific story tells of traveling monk Mu Chou meeting another monk and asking him where he is coming from. The monk simply shouts in return — to every question or comment Mu Chou makes — and Mu Chou, sick of this nonsense, calls him a fraud and a phony and hits him with a stick. He uses the term “a dragon head with a snake’s tail” when abusing the other monk. Which, in this context, is closer to a “wolf in sheep’s clothing” in meaning.
