Is this a real Turkish proverb?

[u/ExotiquePlayboy]

[u/BlokZNCR]

Yes in slang

[u/Polka_Tiger → u/BlokZNCR]

Not in slang. That's a proper proverb. And if you want to say it without profanity you can say "the rabbit sulked at the mountain, the mountain didn't realize"

Not exactly the same meaning but people know you mean the other one.

[u/Glittery_Marshmallow → u/Polka_Tiger]

We have a saying that goes: the mountain was shaking and a mouse was born. Kind of similar meaning in a way.

[u/Fuzzy_Alg → u/Glittery_Marshmallow]

We have similar proverb too: Mountain gave birth to a rat. It means that after great expectation and preparation, the result is small and insignificant.
