Bozo

wiktionary
Attested since the 1910s in American English, of uncertain origin. [1] [2] The term may derive from Spanish bozal, a term originally for a recently-imported slave and then "someone who speaks (Spanish) poorly". [3] The term is older than Bozo the Clown, introduced in 1946, [3] and derivation from French bouseux/bu.zø/, a derogative term for a farmer equivalent to "bumpkin" is phonologically problematic.
