PLONKA = The British and Australians use the term "plonka" as derrogatory slang. For example, they might say "What a plonka!" in disgust referring to an inept and annoying person. It means, roughly, a very stupid person. This appears to be a variation of the more common term plonker, which is used likewise.
This use seems to have been popularized by the popular British television sitcom "Only Fools and Horses" (c. 1981 through 1992), in which the main character Derek "Del Boy" Trotter often referred to his daft brother Rodney as "a right plonker".
