Shit Attack 

when you feel very uncomfortable in your lower intestine, after an hour or so of farting and discomfort you shit your brains out. result: feeling very uncertain while shitting meaning you think you may throw up but you are not sure while filling your toilet with diarrhea. also if you shit long enough you asshole will feel like its on fire for roughly 15 mins.
the best way to make the feeling go away it just shit it all out.
it happens to everyone and its about to happen to me....

example: eating bad food or foods that dont mix. your body is able to digest them expect they come out in liquid form. it hurts for a long time before you actually shit. during that duration you have loud and stinky farts.
its called a shit attack because of the diarrhea that spews from the asshole
this all is sadly happing to me now and i know what im in for.

to prevent this eat bread with your meals to make nice solid and smooth shits lol. also don't eat old food or mix things like only chocolate and water on an empty stomach.

it happens to everyone once in a while

Shit Attack Awareness Level 

This scale of measuring ones need for a number. 2 (i.e. dropping the kids off at the pool) is defined from a number between 1 - 10, with 10 being a level so strong you actually crap your pants with the occasional loose bowels (diarrhea).

We could tell by the way Fredrik was running past us towards the toilet that he at least had a shit attack awareness level 7 bordering on 8. The brown stain on his pants definately helped justify this..

Ketchup: And?

Beef: Its coming out of my ass right now, and I only had it a while ago! I'm having (yet another) Big Mac Shit Attack!

Ketchup: Ouch. I feel bad for the toilet after this one.

Beef: Yeah, me too.
