      I figured it came from a similar expression like “happier than a pig in shit” implying the person is happy about something they really shouldn’t be happy about.

      Hm that kinda makes some sense. I have to wonder who ever saw a possum do that though. They aren’t much for being seen :)

    According to urbandictionary, if someone is shit eating, it means “To be exceptionally smug, full of oneself.”

    I guess, it’s a type of grin that makes someone assume the person is like that.

    I always figured it was meant to describe the kind of person who could sit and happily eat an entire plate of shit, and yet still think they’ve got things more figured out than anyone else.

    Because when your boss is doling out shit for everyone to digest, everyone sits there with a wide smile on their face to show how impressed they are with boss’s fecal dissemination talent.
