A trip to bathroom require the use of only one wipe; which, although may be a sign of not having enough fiber in one's diet, it is definitely a wonderful thing.

When something smells bad, as in a dumpster or outhouse, but has a tinge of something a little extra that's almost pleasant. Think of the smell when driving past a cow pasture or of rotting fruit in a garbage can full of trash or even a Honey Bucket that just had chemicals added to prolong the life of its use rather than empty it.
Me: "What's that smell? It's kinda bad..."
Him: "...but not really. It smells like... like... SWEET SHIT!"
