The phrase originates in the 1987 film RoboCop, where it is the catchphrase of comedian Bixby Snyder on a fictional television show watched throughout the movie. Played by S. D. Nemeth, the character repeats it as a crude, crowd pleasing punchline. The line outlived the film as a standalone quote, spreading through movie quote sites, forums and soundboards as shorthand for enthusiastic approval of a bargain. It remains popular because the wording is self explanatory even without the film context.
