TMZ gets pretty litigious with rhyming acronyms, they’re like a trashy Hollywood Disney. So everyone avoids “BMZ” just to save themselves the hassle.

There actually are, they just are not widely known.

BMY is actually Bolivian Meat Yachts, but they always sink so no one discusses them seriously.

BMZ is the abbreviation for the Boston Milky Zebras, a Little League snail racing team. They were recently disqualified though for doping their snails with speed.

We talkin’ about the Bee-Militarized Zone?

BMY is Bristol-Myers Squibb
BMZ seems to be up for grabs though.
