extreamly bad diarhea, symptoms ranging from the squirts, to actual blood comeing out your rectum.

a perfectly good excuse to skip work/church/school/anything, no questions will be asked.
you on the phone : "hey, ummm boss, i can't come in today, i have the bloody flux.."

your boss: "good lord kid, stay home!!"
