What is a stake burger?

Excuse me, but could you please clarify what exactly a "stake burger" is? I'm somewhat familiar with the world of cuisine and burgers in particular, but I haven't come across this term before. Is it a new type of burger that incorporates some sort of steak or meat product? Or perhaps it's a regional dish with a unique preparation method? I'm genuinely curious to learn more about it, as I'm always on the lookout for new and interesting culinary experiences.
