I was going to try to explain it to you, but it's probably better you just watch it yourself.

At first Ke$ha is in the back of a hearse and these guys carry her out of it, she has a veil on her head it's got a real Gaga kind of vibe to it.  Then she's dancing in front of a pentagram, not sure but maybe there's some symbolism there? And there's a lot of eroticy (haha eroticy isn't a word but I can't find another way to say it) people in the background, she also is rocking a gold tooth.  She is definitely living up to her crazy/out there attitude in the music video. I'd definitely rate it PG-13... Check it out!
