sfidiot 

A Stupid Fucking Idiot. More than just a plain idiot, some people are called a stupid idiot, while others that REALLY get you pissed off get the distinction of being a fucking idiot. This is the perfect combination that just rolls off the tongue.

Many traffic accidents could be avoided if SFIDIOTS would just learn to use their turn signals properly!

shidiot 

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.

Smidiot 

Derived from "Smart Idiot." One of those annoying, over-educated, know-everything people that are armed with a bevy of useless facts. They are completely lacking in common sense and charisma. Usually found in their native habitats of Wall Street, or leadership positions in companies that go broke shortly thereafter.

Almost anyone that helped blow up Wall Street firms during the mortgage meltdown. Anyone that worked at Bear Stearns or Lehman brothers. In the movies, the Smidiot is usually an Eddie Haskell type character, a smarmy know-it-all.
