Someone, usually a hippy type, that portrays themselves as a seer of seers a psychic. They are simply put, morons.
Tom thought he had convinced us all about the rise of the Egyptian Empire's return but we all knew quite immediately, he was a Nostradumbass.

An idiot who misquotes and/or mixes up Nostradamus' 'predictions'; also, any lunatic 'doomesday' or conspiracy theorist, especially those with access to a microphone or video equipment. (See: Glenn Beck, Jerry Falwell, Rev. Jim Jones).
"OMG!! Glenn Beck just said Arizona's gonna secede from the United States and become a sovereign nation!!" "Whoa, CHILL OUT dude; Nostradumbass doesn't know what the hell he's talking about."
