What is "dolemite"

Dolemite is a 1975 American blaxploitation feature film, and is also the name of its principal character, played by Rudy Ray Moore, who co-wrote the film and its soundtrack. Moore, who started his career as a stand-up comedian in the late 1960s, heard around that time a rhymed toast by a local homeless man about an urban hero named Dolemite, and decided to adopt the persona of Dolemite as an alter ego in his act.
