It's important to avoid using this phrase as it is considered highly disrespectful and aggressive.
If you're looking for a polite way to tell someone to be quiet, you could use phrases like:
* "Lütfen sessiz olun" (Please be quiet)
* "Biraz sessiz olabilir misiniz?" (Could you please be a little quieter?)
Always be mindful of the context and the person you are speaking to when choosing your words.
