Poo Butter is the nasty gelatinous fluid that forms under the folds of a fat ladies titties on an extremely hot day. The sweat runs down and collects in the dark cooler folds of skin and congeals into a texture similar to cooled bacon grease thereby becoming poo butter.
Mabel, make sure you lift up both titties and wash all the poo butter out from underneath them
