Mega-Poo 

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.

David's mega-poo induced vomiting and blocked the toilet.
