Meaning: The best of the best
Sure it might be an endearing name for the boss, or just literally a really, really big cheese wheel, but this phrase’s origin has nothing to do with dairy’s best magic trick. Since the earliest 19th century, cheese was used as a noun to describe something wealthy or top-rate. "Cheese" originated from the Persian Anglophile phrase, “the chiz,” meaning a cool thing. We’re gonna go ahead and bring that term back. It’ll be da chiz.
