DUMB Starbucks is a parody store that sells the same products and acts the same way as any Starbucks except that everything that it sells has the word "Dumb" in front of it, such as Dumb Iced Coffees and Dumb Caramel Frappuccino. 

It was originally set up in LA by Nathan Fielder and was giving away it's coffee for free, but it was soon closed down by the Los Angeles County Health Department because it was operating without a permit.
