"Columbus Dick" is used to define a penis over 8 inches, named after the endowment of the average male from the city of Columbus, Ohio, following a 2017 study that listed 82% of men in Columbus as having a penis size of 8 1/2+ inches.
When a girl ask if a guy has a big dick, he replies, "Baby, I got that Columbus dick, stop playing with me."
