A low-budget movie with a title and plot similar to a current blockbuster film. [Blend of mock and blockbuster.]
Well, TMZ is not the only assault on Hollywood`s way of life. There`s something worse. It`s called the Mockbuster, as in mock Blockbuster. It`s a cheap send-up of a Hollywood hit done by wannabe filmmakers on a shoestring budget. It`s outrageous because passing off cheesy recycled material as art should be reserved for only the big movie studios.

Early this past summer, around the time Hollywood's 2007 blockbusters were set to make their debut on the big screen, movie junkies could find a film that might, at first glance, have been confused with the box office hit 'Transformers.' Set in a dystopian future that looks suspiciously like an abandoned parking lot, 'Transmorphers' tells the story of a war between humans and an evil race of extraterrestrial machines. Unlike its namesake, 'Transmorphers' has no recognizable actors, no merchandising tie-ins and a garbled sound mix. Also unlike 'Transformers,' it has cheap special effects and a subplot involving lesbians. In short, though 'Transmorphers' features the occasional shape-shifting robot, it bears little resemblance to Michael Bay's big-screen phenomenon.
Yet 'Transmorphers' had its own kind of success, earning back its meager production costs in less than three months. Created by a company called the Asylum, 'Transmorphers' was only the latest in a string of cheaply made straight-to-DVD 'mockbusters.'

Where "Snakes on a Plane" stars Samuel L. Jackson as a U.S. marshal coping with venom at 20,000 feet, "Snakes on a Train" features the much lower-profile Alby Castro (who?) in a yarn about snakes unleashed by a "Mayan curse" aboard a Los Angeles-bound train from Mexico.
"Snakes on a Train" is the seventh in a series of low-budget, direct-to-video "mockbusters" over the past year designed to ride the coattails of big-budget studio releases like "The War of the Worlds," "King Kong" and "The Da Vinci Code."

You also see the word blockbuster used to refer to something that's the opposite of a blockbuster:
Or perhaps hockey historians will ultimately record this thing as a draw, just as Buffalo GM Scotty Bowman did early last decade after a mockbuster trade with Detroit involving six players.
'Great trade,' he snorted two years afterwards, 'nothing for nothing.'
