verb: to convert powdered ("flake") cocaine into rock ("crack") cocaine by combining 2 parts anhydrous cocaine with 3 parts sodium bicarbonate (NaHCO3 or "baking soda").

The resulting substance is a smokable, fat soluble form of cocaine.
Example:
Dee-Boy a straight up baller. He cop fat kis from the combos and step on 'em hard. Then he rock up the yayo and slang it to da heads in the hood.

Translation:
Dee-Boy is a successful pharmaceuticals entrepreneuer. He acquires large quantities of anhydrous cocaine from a major international supplier and processes it into a more conveniently self-administerable form before distributing it to low-income local end users, thus turning a tidy profit.
