A relatively recent development in the BDSM community, a brat is a woman who suggests she is ripe for a submissive sexual encounter, but diliberately and flagrantly torment prospective doms. Brats often dress like young girls, sport Catholic school uniforms or dress like Bratz dolls. Often they band in packs and suggest there is immense pleasure available from the group for the right (and lucky) dominant male. Males must "prove" their dominance to the satisfaction of the group. Most serious BDSM practioners put a premium on total honesty and trust and thus the brat phenomenom has not been welcomed by all.
