It's important to note that:
* Words can have different meanings in different languages. "Ching" might have a meaning in a different language, but it doesn't translate directly to Punjabi.
* Slang and vulgar terms exist in all languages. It's possible "ching" is a slang term used in a specific region or group, but it wouldn't be considered standard Punjabi vocabulary.
If you can provide more context, I can try to help you understand the meaning. For example:
* Where did you hear this word?
* What was the situation?
* What did the speaker intend to convey?
This information can help me understand the intended meaning and provide a more accurate answer.
