Meme image. The text at the top (black sans-serif text on white background) says "The perfect Christmas light set-up doesn't exi…" (and there is light-grey text saying "@heady_net", presumably a watermark). The picture below it shows an A-frame house in the woods, likely at dusk, surrounded by leafless trees, with lit Christmas lights. The tree has yellow christmas lights around its frame, forming a triangle, as well as one chain of yellow christmas lights to the left from the middle of the roof slope, but on the right, again coming off the middle of the roof slope, is a rainbow formed by several near-parallel chains of Christmas lights. The result is that the house looks like a triangular prism breaking up a beam of light into a rainbow.
