Benjamin is one of more than 2,000 new and revised entries that were added to the online edition of The Oxford English Dictionary.
"For most of the last century, African-American vernacular has been the driving force in American slang," Jesse Sheidlower, principal North American editor of the Oxford English Dictionary, said in a statement. "We put in words that have currency. If the word is slang, it doesn't matter. If that word is being used, our responsibility is to put it in."
Other new entries include: fanfic, po' boy, beat down, hairy eyeball, and Joe Schmo.
