What does bewuthered means?

"Bewuthered" is not a recognized word in the English language. It's likely a misspelling of "bemused."

Bemused means:

* Confused or puzzled: "She looked bemused by his question."

* Slightly amused: "He was bemused by their antics."

It's possible the misspelling was a typo, or maybe it's a slang term you've encountered. If you can provide more context, I might be able to help figure out what the intended meaning was.
