Tim Nudd provides the necessary context:
A week ago, a man named Richard Neill posted a rant on Bodyform's Facebook wall, humorously calling out the brand for false advertising—saying his girlfriend doesn't have happy periods like those depicted in the ads, but instead becomes "the little girl from the exorcist with added venom and extra 360 degree head spin." The post has gotten more than 84,000 likes. Rather than ignore it, Bodyform one-upped Mr. Neill with the video [above], in which it pretends to fess up about its pathological lying. … It's an inspired bit of writing and performance, capped off by a hilarious ending. And it's brave to admit, even in the context of the joke, that your ads don't tell the whole story. Not every brand would feel comfortable doing this, or more to the point, have the skill to pull it off.
