Flyer on the wall I'm brighter
Another spin on a common phrase, the fly on the wall. This phrase means that you are just observing without being noticed, much like a fly would. But he is smarter(brighter) and he dresses stylishly(flyer) in bright clothes.
Also, he’s brighter than a flyer posted on a wall. Flyers tend to be brightly colors as to attract attention. But as we can see from the picture, he is even more brightly colored (while posted on the wall).
