The overwhelming feeling of accomplishment and happiness after dropping an enormous deuce. Similar to the itis, renders the person useless for the next 30 minutes as he basks in the glory of his deed.
After a long battle with constipation, I finally took a shit. The PSE (post shit euphoria) that followed left me on laying on the couch enjoying the euphoria.
