What does Boo mean?
/buː/

Boo has two familiar senses in English: it's the classic exclamation used to startle someone or to voice disapproval, and it's also long been used as an informal, affectionate term for a loved one — a usage some trace to the French word beau, meaning "handsome" or "sweetheart."

Boo is short, playful, and a little spooky-cute, equally at home on a black cat with ghostly flair or any pet who's become a true sweetheart.
