What does fughly mean?

"Fughly" is not a recognized word in standard English. It's likely a misspelling or a made-up word.

It's possible that it's meant to be a combination of "fug" and "ugly," both of which are informal slang terms. "Fug" is a more vulgar and informal word for "ugly," while "ugly" itself is considered to be offensive in some contexts.

If you encounter "fughly" in a written or spoken context, it's best to ask for clarification.
