Octillionaire - A person so rich they could buy an octillion tacos and still

A person so rich they could buy an octillion tacos and still have enough left to buy a taco for your mom.

I’m an octillionaire. I just bought a taco truck for my ex.

My dog is an octillionaire. He has a gold-plated taco plate.

I’m not rich. I’m an octillionaire. There’s a difference.
