A type of anxiety immediately relieved with a deep, steamy bowel movement. You can literally feel the anxiety drop out of you with each sphincteral contraction, as the source of your hysterics (i.e.: The Bowel) slides right on out of your neurotic vessel. Full relief is usually felt when washing hands, when the classic "light" feeling in your colon sets in.
"Oh, man, I felt so on edge just a few minutes ago! I ran to the bathroom, let a log roll off the truck, and WHAM-MO!!! My fecal hysteria is all but forgotten."
"Oh, yeah, I LOVE that feeling. Instant relief. I love functioning colons."
