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.
The act of a man exploiting and abusing the raw, dominating power he possesses over a willing but weaker woman to gain heavy petting, sexual release, or to feel boobies.
