The situation that occurs when a man's penile shaft appears ridiculously small when flacid, but grows to an abnormal, if not surprising size when erect.
Michael's penis was 2 inches long when he was at his grandma's house, but later as he watched gay porn, his penile shaft grew to an impressive 10 inches. Michael experienced the Accordian Effect.
