After making love to your partner's anus, you withdraw your penis as quick as possible, which should pull out the receving partner's rectum, resulting in a prolapsed rectum or "pink sock." Then, you find a nearby sock, and defecate into it. Having done that, you then beat or "bop" the prolapsed rectum of your partner. This is tangent of the Cleveland Steamer, hence the use of Ohio in the title.
Prisoners in the mentally unstable section of a prison use the Ohio Sock Bop as the most brutal form of shower rape.
