What is a byda?

A "byda" appears to be a misspelling or a less common term, as it does not have a widely recognized definition in English. If you meant "bida," it refers to a leading character or hero in Filipino films or stories. Alternatively, if you meant "bida" in the context of a slang term, it could signify someone who craves attention or is overly dramatic. Please provide more context for a more accurate response.
