tipitoisten

Could you clarify what "tipitoisten" refers to? Is it a real term in Finnish linguistics or anthropology, a name of a group or concept in a fictional universe, or something else? Any preferred scope (history, culture, biology, linguistics, etc.) and whether you want the article to be neutral encyclopedic, highly technical, or accessible to a general audience? Once I have a bit more context, I can generate a concise, wiki-style article under 300 words.
