Mythbust that shit 

Short for, "Mythbusters that shit!"

Telling somebody to check the TV show Mythbusters as a rebuttal after they wrongly claim a myth/rumor is true.

Especially helpful if they still disagree with you after your first refute.

John: A penny dropped from the Empire State Building can kill somebody.
Brian: No it can't...
John: Dude, I read it online.
Brian:Dude, MYTHBUST THAT SHIT!!!!!!

Mythbustered

To have an urban legend (or myth) being busted by the Discovery Channel show, Mythbusters.

You can't shoot off a lock with a hand gun, like on Big Trouble In Little China, that had been Mythbustered.
