odkadaniu

Could you clarify what you mean by "odkadaniu"? Is it a real term in Polish (regional dialect, slang, or a specific field), a neologism you want documented, or a fictional concept for a creative or educational purpose? Providing the intended meaning or context will help me draft a concise, neutral wiki-style article under 300 words. If you have any preferred angle (linguistic analysis, cultural usage, historical development, etc.), please share that as well.
