The scariest Halloween costume...evah! Beware for very NSFW language. And if you want to skip the language, skip to the 4.30 mark.
And I AM talking about the bootylicious babes with Aphex Twins face.
Or if you want to really scare 'em, cruise the college frat houses whilst playing this...
Also a good costume for young children who apparently live in council flats. Song subject matter is also appropriate.
