Everyday common folk i.e Bottom feeders

Back in the Middle Ages, impoverished townsfolk; whom the King had absolutely no interest nor sympathy for, would have to survive by eating dung and dung only because of their lack of monies. Hence the name "Shit-Munchers".

Someone that’s talking a bunch of shit

In which a man shits into a womans mouth, where the woman wipes it over her self while digesting some too.
