If you could provide more context or an example of how you've heard the word used, I might be able to help you find the correct meaning.
For example:
* What is the context of the word? Are you reading it in a book, hearing it in a conversation, or seeing it online?
* What is the word used to describe? Is it a person, an object, or an action?
With more information, I can try to help you understand the meaning of "buggi."
