Mockney (a portmanteau of "mock" and "cockney") is an affected accent and form of speech in imitation of cockney or working-class London speech, or a person with such an accent. A stereotypical mockney speaker comes from an upper-middle-class background. A person speaking with a mockney accent might adopt cockney pronunciation but retain standard grammatical forms, whereas the genuine cockney speaker uses non-standard forms (e.g. negative concord).
