But only if Nintendo says so.
The company filed a request with the U.S. Patent and Trademark Office in order to trademark the phrase, which they word as “in honor” of the approaching release of Donkey Kong Country Returns. At no additional charge the same PR spiel cites the pop-culture nature of the phrase’s use in music, television and film, which I would naively think reason enough toward why Nintendo shouldn’t be able to trademark the phrase.
Keep in mind I ain’t no lawyer or anything, just a dude walking the wasteland of gaming.
