- “Well guys, you must be so amazingly glad to see me you can’t even find words to tell me what a cool frood I am. ”
- —Zaphod Beeblebrox to Arthur Dent and Ford Prefect[src]
Frood is a common slang word that means someone who is “really amazingly together”, and is an intensified version of 'hoopy'. Ford Prefect was described as such, and Zaphod Beeblebrox used the term frood to describe himself on at least one occasion. This informal term was not used on Earth, and therefor Arthur Dent was unfamiliar with it.
The adjective froody comes from this word.
