@Olivier5,
I didn't see any sexual connotation in that video. These girls were clearly swearing to express anger and defiance to what the writers of the ad see as a male dominated society.
I recently said "**** That!" to a proposed agreement that came through my ex-wife's lawyer. I wasn't proposing any sexual act take place between the lawyer, my ex-wife and/or pieces of paper comprising the legal document in question.. the image of said sexual act never even entered my mind (until I read your post).
I was merely expressing my profound disbelief at what m ex-wife was proposing and anger at how she is dragging this out.
Swearing is often used to express extreme emotions from "Hell yeah!!!" to "Screw yourself and the horse you rode in on.". These expressions aren't sexual at all.
