ponk

Coined by, or at least first recorded in, the works of British author P. G. Wodehouse ca 1923, ponk is an intransitive verb meaning, basically, that something sucks or is really, really crappy.

Wodehouse began using the word in the 1920s when Jazz Age slang was all the rage in England. It is spoken in Series 1, Episode 4 of the BBC comedy, "Blandings," adapted from Wodehouse's "Blandings Castle" book series, 1915-1975.
