desasé

I’m ready to write a neutral, concise wiki-style article, but I need more context. What does “desasé” refer to in this request? Is it a person, a place, an organization, a linguistic or cultural term, or a fictional concept? If you can specify the context or language, I’ll craft a concise article under 300 words. If you’d like, I can also provide a brief disambiguation-style entry outlining possible uses.
