A Sidiot is a city idiot. Anyone who lives in or visits a city and acts like an idiot is a sidiot. It used to be spelled C-i-d-i-o-t....but apparently thats taken (those sidiots). It came to be one day while the Arties were Starbucking. They saw an afrofritter then NeeNeeGee exclaimed "Chel, that's an afrofritter not a squirrel! God, you're such an idiot....like a village idiot, except you live in a city not a village, so your a city idiot...actually, a SIDIOT!" and there you have the awesome story of sidiot. Which is much better than thiers. ha
1. Chel was a sidiot when she fell on her face while getting into the backseat of the car.

2. NeeNeeGee was a sidiot when she dropped the board onto her head.

3. Fooky was a sidiot when she crossed the street when cars were coming at her.

Guy 2: what country?

Guy 1: I just said, Africa

Guy 2: that's a continent idiot

Guy 1: I... I know that, I was only joking.

Guy 2: you're a real schrodinger's idiot
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.

A lighthearted reaction upon receiving disappointing news of some sort. Usually something that isn't a particularly a big deal, esp. when it primarily affects someone else - sort of a mild schadenfreude. Sometimes doubled or tripled, and possibly said in a sing-songy voice for added comedic effect to imitate a muted trumpet, which is how the meme originated.
