To me, the phrase "food porn" is humorous because it implies that images of food itself are arousing, provocative, appetite-stimulating, etc. When you add an actual sexy person into the mix, it gets too literal and the humor is diminished. That said, I don't think the burger itself was very stimulating; it looked like a mess of elements following a more-is-better formula.
Still, who knows, there might be an audience, somewhere, for this kind of thing.
