Proper noun. A guttural dialect spoken largely in Italian-American neighborhoods or at the Jersey Shore by Italian-Americans, largely a combination of stock phrases like fuhgeddaboudit and malpronounced Italian words (i.e. gabbagool for "capocollo") that are passed off as being true Italian. A subset of English that makes real Italians cringe.
