Officially from the latin "mens sana in corpore sano" (a sound mind in a sound body); adopted by California Kar Kulture in the 1960s to describe a particularly "clean" (sanitary) custom job. Rarely used now, which, oddly enough, probably makes it cool again.
Dude just got his lowrider finished over the weekend. Sano paint, not too heavy on the bling.
