Being rich as fuck, ballin' outta control. Racks is a synonym for stacks; a stack being $1,000. Basically, if you stackin' money crazy high, you got racks on racks on racks. Made famous by Yung Chris' hit song 'Racks'.
That nigga Yung Chris might not have had racks on racks on racks before that song, but that shit is a hit, I bet he's rollin' now.

Incredibly large sums of money. But more appropriately, an adjective used to describe something that one possesses in copious amounts.
Justin spent racks on racks on racks last time he went to the grocery store, and now he has racks on racks on racks of Cap'n Crunch in his pantry.
