MythBuster 

The sexual act in which one person holds mentos and coca-cola in their mouth while a partner ejaculates into their mouth. Immediately after said partner has finished the holder will close their mouth and shake their head vigorously in hopes of creating an explosion. Alternately the ejaculating partner may also urinate in their mouth.

If you play your cards right I might just take you home for a mythbuster session.

2. DAMN IT! I pulled a real mythbuster on my car. Shouldn't have tried to drive through that lake.

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.
