Christina Aguilera is a very bad girl ... just ask her. Or better yet, ask anyone who's seen her much-talked-about video "Dirrty" from her forthcoming album, Stripped.

In the clip, the pop tart writhes about in revealing costumes and gets very close with several of her dancers ([article id="1457901"]click for photos from the video[/article]). While that's pretty much de rigeur for pop music videos these days, a few of the concepts are a little more out-there (see [article id="1457893"]"Christina's 'Dirrty' Makes Some Fans Ill, Others Hot To Eat Her Toes"[/article]). While Aguilera and director David LaChapelle may be familiar with the boundary-pushing images that pepper the video, not all viewers are. We decided to pull up a lounge chair, screen the video closely and file a full report.

:02 - Christina appears sporting chaps over underpants, exposing her derriere, a popular look in the sadomasochist community.

:26 - Christina is restrained in a cage, a method of restraint used by bondage aficionados.

:39 - On the wall behind Christina are signs in Thai script that read "Thailand's Sex Tourism" and "Young Underage Girls" (see [article id="1458223"]" 'Dirrty' Christina Aguilera Video Thai-ed To Sex Industry"[/article]). Self-explanatory.

1:40 - Suddenly, Christina is dancing in a modified schoolgirl outfit, which indicates "age play," in which adults take on the role of children while acting out fantasies.

1:46 - We see a woman in a hooded mask. While this mask appears to be a Mexican wrestling mask, it is common for masochists to wear similar headgear.

2:34 - Christina and the woman in the mask engage in a boxing match. When women who aren't trained pugilists engage in a match for a group of men, it's known as foxy boxing. The focus is not on the athleticism.

2:52 - A male dancer rubs his groin on Christina. Let's move on.

3:05 - Redman, dropping by for his guest joint, passes by a man holding a chicken, standing near small cages, hinting at an afterparty cockfight.

3:25 - Redman also passes a smiling female bodybuilder. A small subset of men fetishizes the muscular body type.

3:29 - The viewer is treated to a scene of male/female mud wrestling. For many years, the sport of wrestling has been sexualized in bars and clubs with barely dressed women taking on men in pits of Jell-O, pudding, or in many cases, mud.

3:33 - Redman spots a fire-eating woman. We're not sure that's a freaky sex thing, but it's certainly freaky.

3:36 - Redman, still rapping, passes a group of people in bunny and chicken costumes, such as you might see at an amusement park. This would seem to be a shout-out to the furry community, people who are sexually attracted to furry characters and often dress like them.

3:46 - Christina and her dancers are getting wild in a men's room. They frolic near urinals while being sprayed with water. This seemingly unhygienic move may be a reference to "water sports," a term for those who find pleasure in getting wet in, shall we say, "unconventional" ways.

4:31 - Finally, a perfect endnote. Christina is spanked like the naughty girl she is.
