The Columbus Cauliflower is an act during anal intercourse where the engaging members do not use lubrication. When the penis is initially shoved into the anal cabin, then snatched out at an alarming speed. The result of said action is an "inside-out" anal cavity, resulting in the imagine of a cauliflower, thus, the name Columbus Cauliflower. The origins of the name come from the city of Columbus, Ga, where the sexual act became popular among high school adolescents in the late 2000's.
My girlfriend forgot the KY lubricant, so I gave her a Columbus Cauliflower so that she never forgets again.
