I've heard people described as ぬるオタ （ぬるいオタク） "mild otaku" as well as 超【ちょう】オタク "super otaku". My question is whether there is a sort of "general set" of these sorts of words (maybe similar to the prefixes like: super-, ultra-, mega- etc.), or whether what I have encountered is really just creative language use.
Are there some useful terms to describe a kind of "spectrum" of enthusiasm?
E.g. Low to high: ぬるオタ, （普通【ふつう】の） オタク, 超【ちょう】オタク , etc.
It has been suggested that gachi- "serious/diligent" may be on par or above chou-.
Edit: Even phenomena like "Okatu-dom" are perhaps best not described as a linear spectrum. We could theorize dimensions like (kakko ii > kimoi), (dedicated > casual), etc.
Thanks for any help!
