A "Cavababe" in the Ravaged Land, belonging to a tribe of primitive, attractive cavewomen who were systematically attacked and kidnapped by the tribe of Frank the Brusher. Forbush Man accidentally reached the Ravaged Land, then accidentally saved a member of the tribe. Boom Boom and her friend Dawn convinced Forbush to confront the Brusher. He succeeded at chasing away the raiders by convincing them that modern women's company was not at all the bargain they thought, claiming in the process that Cosmopolitan magazine said so. Boom Boom, Dawn and the other cavababes were very disgruntled because Cosmopolitan never said that, at least not in that sense, and Forbush had behaved chauvinistically; they chased him away, until he had to join the Brusher's tribe.
