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.
