Where one voids his or her bowels, only to find, by wiping one's anus, that no evidence of the event remains. Not as rare as immaculate conception, but still magical.
Cletus found, after taking a huge shit, that his first wipe was completely clean. "Hallelujah!" He exlaimed, "Immaculate defecation!"

The holy grail of bowel movements. You take a big ol' dump, and you wipe. Then you look and see that the toilet paper is clean, and no turd is in the toilet. So clean, it's almost divine.
The Immaculate Defecation is the best poop in the world. No turd to clog the toilet, no mess on the TP to worry about. It's like God took the dump for you.
