If what you're talking about is this:

to do something that spoils someone's plans

We have idioms 水【みず】を差【さ】す and 腰【こし】を折【お】る in Japanese.

水を差して [apology words] …
水を差すようで [apology words] …
水を差すようなことを言って [apology words] …

(話の)腰を折って [apology words] …
(... and so forth ...)

while in [apology words] you can fill (in the order from casual to formal):


The difference between the two is, 水を差す is more like spoiling the fun, and 腰を折る is more interrupting the stream.

  • Are these commonly used or would they make me sound like an old man? I can never tell between the former and the latter. Feb 27, 2016 at 18:22

  • @strawberryjam They're not that a young child could say, but you don't need to be too old to use them. Actually, I'm a ゆとり世代 but I expect everyone around me uses and understands these words. Feb 28, 2016 at 6:30
