Supernova

Mountain Dew ran a contest/promotion to add a new, permanent flavour to their already-impressive lineup of drinks consumed exclusively by those playing way too many video games. As part of the contest, they released four different flavours as limited-time releases and one would be chosen for permanency while the other three were retired. As a side note, the contest was an attempted follow-up to the popular Hitler did nothing wrong fiasco. Mountain Dew needed a win.

One of the four flavours was Supernova, and it was very quickly chosen as the preferred option of the Good Dudes. It was tasty, it had a catchy name, it had it all. The Dudes, led by James, began devising campaign slogans that could be used to sway undecided voters in advertising. The slogans, too ambitious to target the other three prototype flavours, went after more established and popular options: Supernova ultimately didn't win the contest despite the many bottles purchased by the Dudes, and true to the stated stipulations, was never seen again. Another failure from Mountain Dew, who will be doomed to be forever drank only by nerds on the weekend, and be known best for a put-down on The Simpsons.
