I'd say it is definitely girls.
They are the ones famous for loving to go shopping, and they are the ones who tend to spend a ton of money on useless little things like nails, expensive hair treatments, buying new handbags when they have more then one already, buying many shoes, etc. All to satisfy there whims which come and go like the flick of a thumb. lol
