To help me understand what you mean, could you please provide more context?
For example:
* Where did you encounter this word? (a book, a conversation, online, etc.)
* What was the context of its use? (What was the sentence about?)
* Do you have any other information about the word? (Is it related to a specific field or activity?)
With more information, I can try to help you figure out what "kudlung" might mean and how to use it.
