The Raydude is an extremely hairy and smelly creature which stalks forests, woodland and the occasional garden shrub in areas of northern England, particularly South Yorksire and Lancashire. The Raydude has been known to attack and viciously extract the virginity of many a wandering child. It bears a strong resemblance to Slash (Guns N Roses guitarist), although significantly less clean.
