A "variation" of English entirely made up of slang and southern word shortenings. It is generally spoken in the "hood" (neighborhood) and has almost no defined syntactical structure. Also of note is the almost complete lack of conjugation of verbs ("I be", "she be", "thems be", etc) and the mixing of pronouns. When spoken in any educated circles, its usage usually screams "I am illiterate."
Jive/Ebonics: "Sheeeeiit, foo, I'z be doin' dat shit an' shorty be axin me fo' sum' scrilla."
English: Shit, friend, I am doing that stuff, and my girlfriend is asking me for some money.
