A Reddit thread called "Did you ever think you were going to die from a shit?" sparked a lyrical/scatological series of reminisces of epic dumps, including a two part series by ErikPDX recalling a storied moment of colonic glory following a period of post-surgical bedrest during which he consumed enormous amounts of painkillers and protein shakes without bestirring himself to relieve himself, until such time as his body could stand no more. Mr PDX included a picture of the result. I beg you not to click the link in his post which leads to it.
My entire body tingled. I felt lighter. I was covered in sweat, and breathing heavily. I felt high, delirious, in shock and awe. Great waves of increasing euphoria washed over me. Feelings of amazing pleasure I simply cannot describe. I felt as if I was bathing in a golden light of goodness. This was a transcending event. I felt like I had just touched the universe itself.
