A shit so big that it causes pain to the creator and causes plumbing issues to the toilet simultaneously. Often this can come naturally or be induced using copious amounts of ginger ale, caffeine, foods heavy in fiber and starch and sitting/laying in a folded position.

Mega Poo Caca is almost like explosive diarrhea. But 10x more powerful. If you think you will go Mega Poo Caca one day, DO NOT USE A SMALL RESTROOM. If you do, you will drown in your own poop and die. Mega Poo Caca happens to 1 out of 150 people! Stay safe. P.s. Mega Poo Caca is usually used as an over exaggeration.
