Raunchy: In a manner likely to attract the tag 'wee hoory nell', dressing old mutton in patent leather and/or torn hosiery and calling it lamb, having the facial expressions of a wombat with severe cramp.

Prodigy - Smack my Bitch up
Lady Ga Ga Feat Beyonce - Telephone
Beastie Boys - Fight for your Right (Revisited) 25 mins long - Genius stuff!
