"Slang" is an array of all words rejected by popular dictionaries, for 1 reason(s). The first reason is due to the fact that hateful "slang" words "offended" the dictionary's editors, but only because such words described their girlfriends.
However, slang does not mean to sell drugs. Many think that in Dem Franchize Boyz song "White Tee", they reference drug trafficking using the word "slang" (I bang in my white tee, I slang in my white tee). Rather, slang (verb) mean to front someone by using slang words to insult them, and "bang" referring to gangbanging.
Italian, Spanish, French, Portuguese, and Romanian are all slang versions of Latin.
