Well, the clown was probably named with the American English slang word "bozo" and I doubt if his name is related to the south Slavic examples of Božo.

My guess would be that Božo is a shortened form of south Slavic names such as Božidar and Božislav. (see BOŽIDAR)
(P.S. I have no idea why BOŽIDAR and Božidar aren't creating links since the name is in the dictionary on this site.)
