Rengimo

Could you provide some context for "rengimo"? It isn’t a widely recognized term in my current references. Do you mean a word from a specific language, a place, a person, a cultural practice, a concept in a particular field, or a fictional/unofficial term? Any additional details (region, field, or intended meaning) will help me produce a concise, neutral wiki-style article under 300 words. If you’d prefer, I can also draft a generic template or a fictional entry, clearly labeled as such.
