Here are some examples of how it might be used:
* "Eh kharku cheez hai" - This means "This is a worthless thing."
* "Tere kharku baatein sunn ke meri dimaag kharab ho gayi" - This means "I got annoyed listening to your silly talk."
It's important to note that "kharku" can sometimes be considered offensive, depending on the context and the tone of voice.
It's best to avoid using this word unless you are very comfortable with the Punjabi language and culture.
