The action of taking a crap, shit or piss in a place where
there are no proper facilities, such as a toilet or tissue paper. It is usually urgent, when
there is no time to seek out better accomodations. Sometimes it is uncontrollable, which
makes for a better story
to your friends at cocktail parties.
1) I made a mistake of eating a box of prunes before
Mountain Biking. I had to "go caveman" in the woods with
leaves and bark.
2) Man did we drink too much last
night after work! I had to "go caveman" in the subway.
3) There was no paper in the outhouse; I had to wipe my ass with
my underpants and left
them in the garbage can.
