【モンスト】あけおめ【ぺんぺん】

is a New Year’s greeting often used in the Japanese mobile game Monster Strike (モンスト). It is a shortened version of the phrase “あけましておめでとうございます” (akemashite omedetou gozaimasu), which means “Happy New Year.” The addition of “ぺんぺん” at the end is a humorous play on words, as it sounds similar to the English word “pen,” but has no specific meaning in Japanese. This greeting is often used by players and developers of the game to wish each other a happy and successful new year. It has become a popular phrase within the Monster Strike community.
