A rapper who supplies dope, or in other words "sick" or "ill", rhymes.

It's a pretty clever spin on the expression "dope dealer," putting a pun on the word "dope" which can mean either drugs (including heroin and crack/cocaine), or it can be complementing something.

A cultural and aesthetic mind-state that prioritizes making money, even as an “underground” or “radical” creator. The work isn’t made for money, but it’s the money that matters the most.
