A muffin that does not contain (throughout its inner cake) any of the ingredients displayed on the top of the muffin. Term can be applied to people in an organisation who appear to do work but who achieve little.
You buy what looks like a delicious fruit stuffed muffin but find that inside it is all cake and no fruit. It looks good but delivers nothing. It’s not a muffin, it’s a nuffin.
