(also spelt "bonkie, bonkey"), a black person who attempts to behave (or assume the airs of) a quintessential, white person. The bonky is oftentimes seen: wearing wire-framed spectacles and a flannel shirt tucked neatly into a pair of khaki trousers, assuming a nasally and overworked white, suburban accent; smiling unhesitatingly; and boasting a European name (i.e. John D. Bailey). In popular culture, Carlton Banks of the sitcom 'The Fresh Prince of Bel-Air' would be an archetypal bonky.
After the bonky had told Winston to 'have a super day,' he leashed his Yorkshire terrier and began to walk around the park.
