What is a boss render?

Excuse me, could you possibly clarify something for me? I've come across the term 'boss render' in a recent article, and I'm having some difficulty understanding its exact meaning. Is it related to graphics rendering in the context of computer animation or video games? Or perhaps it's a term specific to the world of cryptocurrency and finance? Could you provide a brief description of what a 'boss render' is, and how it might be used or referenced in a relevant field? I'm quite curious to learn more about it.
