A sex act in which a girl spreads her ass cheeks apart like goatse, while her partner pours milk and Hershey's chocolate syrup into her open anus. The girl then proceeds to twerk like Miley Cyrus until chocolate milk is made, which is then consumed by the couple.
After getting bored performing the Cincinnati Bowtie, the freaky couple moved to the Cleveland Steamer and then began making Columbus Chocolate Milk.
