Starbucks is celebrating the 20th birthday of the Frappuccino (ever heard of it?) by releasing the Birthday Cake Frappuccino for 5 days (March 26-30). So if you have a spare 800 calories to waste, go order one. The drink is a combo of vanilla bean and hazelnut topped with raspberry whipped cream and regret. On the bright side, now you don't have to buy your bestie a cake for her birthday, just buy her a B-day Cake Frappuccino to tell her you don't give a shit about her diet.
