The marketing geniuses at Doritos have launched another brilliant promotion – asking their customers to name their new mystery flavor, currently called X-13D, which is packaged in a can’t-miss black bag. You have to taste the chips to figure out the flavor. The winner of the contest will become a “Doritos Flavor Master” and get to taste test the latest snack innovations from the Doritos brand, as well as receive free Doritos Tortilla Chips for a year. (What is that, like 3 bags a day for a hungry teenager?) For more details, go to this annoying Flash website, or (how’s this for Gen Y…), text “X-13D” to 24477.
