prostoktem

Could you please provide more context for the term "prostoktem"? I’m not aware of a widely recognized topic by that name. Is it a concept in a particular field (for example science, linguistics, geography), a brand or product, a surname, or perhaps a term from a specific language? Additionally, do you want a real-world encyclopedic article or a fictional/brand entry? Any details on the intended audience or required length would help me craft a concise, neutral, wiki-style article under 300 words.
