Over-priced British clothing brand, mainly aimed at apparently rich university and private school students more commonly known as Rahs. However, this brand is really only worn by those without the money or style to buy real designer clothes such as Armani, Dior, Ed Hardy etc.
Rah Girl: "Oh Tarquin darling, have you seen the latest Jack Wills handbook, there are some gorgeous trackies in there for only £70!!"
Rah Boy: "I have Henrietta, isn't Jack Wills so wonderful for rich, stylish folk such as us!"
Genuine wealthy person: "If you did have money or style, you would be wearing proper designer clothes, stupid Rahs!"
