Not as in the clown Bozo.
But as in this guy I vaguely knew named Bozho who went to my grade school and my cousin's grade school.
I kept thinking about the clown whenever I heard this guy's name, but in high school, he played football and looked decidedly tougher in his football picture. He was playing foo-ball foo-ball! Must prove masculinity! GRRR.
His smirk reminded me of the intensity captured in this Olympics Nike commercial.
Bozho would be out for your blood, motherfucker.
