The term "zerbet" was used by
Bill Cosby in his role as Dr Heathcliff Huxtable in The Cosby Show i
the 1980s to describe a "raspberry", his stage daugther Rudi had given him. A "raspberry" or "zerbet" is the act of putting one's lips against a body part, principally the belly, and
blowing air. A tickling senstion ensues.
