The term "Chikuwa Great Deity" (ちくわ大明神, Chikuwa Daimyōjin) is a Japanese internet meme and slang term, not a traditional deity from Japanese mythology or Shintoism. It originated from a Japanese online forum (2ch) copypasta in 2008 and is used as an equivalent of "nobody" in Japanese internet slang
In the original copypasta conversation:
Since the interjecting phrase had no relevance to the conversation, "Chikuwa God" came to mean an unknown or irrelevant entity, or a "nobody".
The juxtaposition of a mundane, everyday fish cake with a grand religious title creates the humorous and absurd nature of the meme.
