Heavenly shit
A type of shit you take in ultimate privacy and comfort after having to consume and digest excessive amounts of food or melted cheese. The feeling having to unload the shit is so refreshing and heavenly (hence the name "Heavenly shit") that it usually has you sitting on the toilet for more than 10 minutes at least.
"After the buffet, I took a heavenly shit."
"I feel so much lighter now that I took a heavenly shit!"
