A flatcocker (see 'flatcockers') who ALWAYS assumes (or wants to, anyway) the
dominant position. And, unlike a flatcocker, who usually only uses the prehensile pubic and hip bones, the bullcocker
sometimes enlists the help of instruments to further her mission and to better give satiation to the
submissive femme that is the object of her affections.
"Did you see how that bullcocker worked over that submissive femme in the movie? I didn't know if that
little lady would be able to
handle that onslaught. That REALLY turned me on!" 'Bullcocker', as well as the word 'flatcockers' has been in use for many, many years here in the Southern
United States.
