Shit/Idiot combined, The word was originated when I was watching Freddy Got Fingered (horrible movie)and somebody yelled "idiot", it sounded like "shidiot", but just so that everybody knows I made it up, me!

A mixture of shithead and idiot. Often known for as being an insult, definately not a compliment, and NOT defined by the following person above/below/whatever, it was a common swear word my grandfather would say when driving on the road and running across a 'shidiot' who obviously didn't know what they were doing.
That stupid shidiot doesn't know how to drive! The light isn't going to get any greener, damnit!

I can't stand that asshole, he's a stupid shidiot.

When a bunch of dumbies in your class just won't shut up and you're trying to read Hamlet (with no success) and you try to insult them while asking them to be quiet politely but they are too retarded to listen.
