A true Milwaukee Brewers’ Fan…
We cannot investigate the bona fides of the Milwaukee Brewers. If you are a TRUE fan, you will rely solely on their deduction!
bona fides \ BOH-nah FEE-des \, noun;
1. Good faith; the state of being exactly as claims or appearances indicate.
2. (Sometimes italics) (used with a plural verb) the official papers, documents, or other items that prove authenticity, legitimacy, etc., as of a person or enterprise; credentials.
Origin: Originally bona fide , bona fides was accidentally pluralized by the 1830s and subsequently was used as a synonym for credentials.
