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 I went 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 Go Caveman and wipe my ass with my underpants and left them in the garbage can.
