There is a Chinese idiom 乌鸦嘴 or Crow's Mouth which means saying something unfortunate, and then it comes true. For example:
Anthony: I think there will be a thunderstorm later
[Some time passes and there is a thunderstorm]
Brandon: You and your crow's mouth, now there is really a thunderstorm!
Otherwise it is just a response to a negative remark.
Cody: We don't have many customers these days. I hope our boss will not cancel the year end bonus.
Donovan: Watch it, you and your crow's mouth!
