A fictional, vestigial Orifice hidden deep in the anal cavity. Seldom cleaned and commonly burdened with excessive waste material, it is generally understood to be an undesirable hole.

The Jucuntius orifice is located several inches deep into the anal cavity and is 2 inches deep x 1 inch wide.
Oh! I'm an A-hole, well you're a J-hole!

The J-hole (The Jucuntius Orifice) is worse than the anus.

What Bob Ebeling's superior told him not to be when he reported that the Space Shuttle Challenger had unsafe rocket-boosters.
I'd rather be called a donkey-orifice a million times than not speak out against a design-flaw that would likely cost the lives of seven astronauts.

Refers to where all of your bodily-openings are all "venting" at once --- i.e., you're simultaneously sneezing, coughing/gagging, farting, etc. --- and so you are unable to adequately monitor them all at once to prevent messy "oopses". It's not unlike what happens when a piece of complex equipment suffers a major malfunction and causes alarms and indicator-lights to go off all over the place, and so you cannot possibly keep track of them all or deal with many multiple issues at once.
Anytime I feel a bout of orifice-outflow overload coming on, I simply shed all my lower garments and race to da nearest WC --- that way, I am safe from any "accidents" because any offending fluid/matter will just go down da toilet or into da sink, rather than soiling my clothes or anything else in my general vicinity. And so far I have yet to be cited for public indecency --- seems dat folks would prefer having to temporarily see me in my birthday-suit rather than mopping up copious quantities of puke/poop afterwards... they merely bring me my pants and briefs again from where I'd haphazardly flung them in my frenzied headlong dash for da crapper, so dat I can re-dress myself in privacy before emerging from the bathroom-stall again.
