"Sub best" is not a widely recognized or commonly used phrase in the English language. It does not have a specific etymology as it does not hold any significant historical or linguistic meaning. It appears to be a combination of the prefix "sub-" meaning "under" or "less than", and the word "best", which means the highest quality or most superior.
