A combination of the Cleveland steamer and the steam roller. The Cincinatti Compressor is achieved when one forcefully pushes a poo onto another's chest. The 'compressor' clings their backside to the 'compressee's'' chest. While forcing the defecation poo is compressed leaving a dense wad of excretion on the person.
Damn man the Cincinnati Compressor I gave that chick last night left remnants in my ass hair. I guess I should eat more corn.
