taking a nice satisfying dump. I mean.... the kind that takes your breath away (and not 'cause of the stench either, although that's a sign of a good dump). Just a great, relaxing feeling, ending in you being a few pounds lighter.
It's even better if you're not expecting it to be that good. You know.... you head to the bathroom, thinking that you're about to unload your standard cargo, but it ends up being a cathartic experience (no pun intended, for all you medically-smart people).
Taking a dump so satisfying is like smoking a great cigar, then sorta being sad when it's gone.
One of life's simple pleasures.
