A very skinny or scrawny looking person of the male gender. They are easily recognized by pencil -sized arms, sunken chest, and emaciated faces. The definition works best with those who believe they are actually muscular, have a nice body. They are usually found accentuating their pathetic features by wearing muscle shirts,daisy dukes, athletic clothing, etc. The saying is derived from the width of a "scratch in the wall"
Look at that scratch over there with the 10 pound dumbells. Who is he foolin..........he thinks he is hulk hogan with that tank top on. He looks more like a heroin addict than anything.
