A word that means "revelling in being dirty"

For example, that wonderful feeling you get when you have been camping for three nights without a shower. Or when pulling apart and eating a crab with your hands. Or when you stand out in the rain on purpose.

I'm looking for a word that has a similar vibe to "hedonism", "debauchery", but with less sexual connotations and more emphasis on actual dirt. "Carefree" or "primal" would usually fit in this context, but not precisely.
