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.
Rappers like
Andre Nickatina, Mac Dre, and rap groups like
RBL Posse are
all dope rhyme dealers.
