Need HELP finding this song!

So there's this song i once heard in a video which was not so appropriate for children and since then i can't get it out of my mind. Can anyone help me and tell me what song it is?

OK so it looks like the video was taken down... luckily i saved it in order to convert it to mp3 xD

So here is the sound only (since all the filehosters i know wont let me upload the mp4 file) uploaded by myself... hopefully this one will last a little longer:
