Top Definition
An exclamation used when disproved of something because of an episode of mythbusters. Often used in arguments between two or more people when one person says something that they beleive to be correct and another begins with "no, I saw an episode of mythbusters..."

Usually a bad thing because the winner of the argument had only to sit on their ass and watch television to win the argument.
Dad: John, roll your window up so I can turn on the AC.
Son: I don't feel like it.
Dad: Damnit, I want to save gas so roll up the fucking window.
Son: No dad I watched an episode of mythbusters and they did a test and it's cheaper to drive with the windows down.
Dad: Fucking mythbusters.
