Shitstorm:

Shit: Well, in this case something extremely annoying
Storm: In this case: Something ambushing you

A shitstorm is something that is extremely annoying which is ambushing you...

Also a word used in MLG Stranger Danger

Bronies Australia.

When a bunch of horrible things happen to you in one day.

Can mean a variety of things, like a long string of VERY unfortunate or horrible events in a short time, but mainly used on internet forums to describe threads full of flaming, raging, trolling, etc all in one. Generally about religion vs atheism, ponies vs anti-pones, furries vs anti-furries, etc.

Its like a shitstorm flying different shits at your face like horseshit, bullshit, and holy shit

A type of Shit everyone has at least once in there life. Not to be confused with the much smaller Shart. However a Shart might be an indication of said Shit Storm Approaching. Multiple cans of air freshener and possible wetting of toilet paper to clean after are good indications. This is the shit of all shits and is most unpleasant. Maybe accompanied by stomach pains and or uncontrollable vomiting if the Shit Storm is from food poisoning.

When you throw shit at a really fast fan making it fly everywhere.
