(interjection) An interjection used among Pokémon fanatics to replace "Oh my God".
The reason why Arceus replaces God is simple: Arceus is the Pokémon responsible for the creation of the Sinnoh region, and possibly the whole universe (Pokéverse, if you
may) according to myths around the
world of Pokémon. His
legend dates back to Generation 4 (
Diamond, Pearl, and Platinum). Arceus is also called "The Original One".
Arceusism is a polytheistic belief system. According to said myth/religion, Arceus is said to be born from an egg, emerging from a vortex, and then created the Legendaries of
time, space, and antimatter: Dialga, Palkia, and Giratina, respectively. When mankind started inhabiting Sinnoh, he created three Pokémon to give humans knowledge, emotions, and willpower.
The term, in real
life, is used as jargon among fans, as reversed verisimilitude to the Pokémon universe. It is also used online where "Oh my God" might provoke a number of religious and/or sensitive
people.
