That intestinal rumbling that occurs at the most inopportune of times, and is unequivocally indicative of a loaf brewing inside your intestinal tract.
While driving down the interstate, there was no obvious reason to take a pit stop; however, after approaching the sign that read "Next Service Area - 24 miles," then the onset of intestinal distress occurred, as I passed the sign.
I clenched my ass cheeks as tightly together as my gluteal muscles would permit, rolled down the windows, turned off the heater and radio, and asked all occupants to "shut the fuck up" until these embryonic manifestations of defecation subsided. Unfortunately, this didn't happen, as I unleashed with a rectal fury and shit my drawers!

Not to be confused with self-deprecating humor, self-defecating humor is NOT funny. A joke that bombs like a dump of crap.
Example: A joke about your own foibles that stinks!

Sorry,Man, I hate to admit it, but I like PB&J with bacon even though it always gives me gas. (Your admitting that is self-defecating humor.)

Too much information, Dude!

The synchro-defecation theory holds that the defecation patterns of individuals who live together tend to become synchronized over time. The phenomenon is glaringly evident when said individuals share one bathroom.

Similar to the McClintock effect, the theory that the menstrual cycles of women who live together, such as in homes, prisons, convents, bordellos, dormitories, or barracks, tend to become synchronized over time.
