A simple warning system named in homage to the Defense Readiness Condition aka defcon. Shartcon is also present at 5 levels, whereas shartcon level 5 would mean only a slight chance of a possible shart. Shartcon level 1 would entail that one is in eminent danger of sharting shortly, and should proceed to the nearest bathroom just in case. It is an early warning system aimed at helping normal citizens avoid shitting the pants.
Dude, I drank alot of jager last night and just grubbed some taco bell...I'm operating at a shartcon level 2. Better pull over, just in case--this fart feels dangerous.
