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.

Past tense of Caveman - when a girl is blowing a guy with a big cock, and the guy pulls away and swings his prized manhood back and forth while whipping his chick across her head with his big erect cock...like a caveman does to his woman when he hits her across her head with his big club.
A Caveman Diet consists of basically two food groups - meat and leaves. Many believe this type of diet is optimal for humans since that's what we evolved on for tens of thousands of years. Beyond the ingredients, an important part of the Caveman Diet is the method of food preparation. As a rule, everything that can be eaten raw is eaten raw. Cooking methods such as deep-frying or marinating are bypassed entirely. If the meat must be cooked - it's lightly seared and eaten rare. The eggs are sucked raw and the milk is drunk fresh only. No cheese, no sour-cream, no ice-cream. Hi-Carb foods like breads, grains and pasta are left out almost entirely.
This low-carb diet is also effective in rapid weight-loss and muscle gain.
