|Several theories exist:
- Maybe from Spanish bozal, a term used in slave trade and meaning "one who speaks Spanish poorly", which originates back to circa 1910.
- First used in American English as a vocative, from Spanish vosotros (“you”, informal) m pl.
- After Bozo the Clown, a clown character very popular in the USA in the 1950s.
- After Anselm of Canterbury's usage of the early continental European Germanic-origin personal name Boso.
- Maybe from French Bouseux (boo-zeu), a derogative term for a farmer, equivalent to bumpkin.
