West Midlands insult similar to chav. Origins are uncertain but it is thought to be an abbreviation of the phrase riff-raff, and localised use in Bromsgrove dates back as far as the late 1980s, if not earlier

Can be both a noun (riff), referring to the antisocial underclass, or an adjective (riffy), meaning something cheap, scummy or gully gully.

Riff (verb, -riffed, -rifâ‹…fing. Informal): The art and science of making fun of low budget B-Movies by making snide and/or sarcastic comments (regarding the poor quality of the film's dialogue, acting, plot, shoddy film design, etc...) at the movie or television screen while the movie is running in the background. The comedy can be either high brow and esoteric or low brow and of the bodily branded humor.
The comic geniuses of MST3k brutally riffed upon the B-Movie schlock sci-fi/horror film "The Giant Spider Invasion." (1975) I don't know if the director was here to witness them shredding his movie, would he cry with shame or laugh until he peed his pants.
