Get the shit on a biscuit mug.
A by-product produced by mostly old people who wear diapers, as well as babies. The shit biscuit is formed when they shit themselves, but doesn't clean up or get changed right away. Over time, the turd is flattened out (from sitting on it) and eventually hardens into a dried out biscuit or cookie-like turd.

Being called a 'shit biscuit' isnt great though its a more polite way of being called a shit <unt.

Its similar to being the last biscuit in the tin that noone wants, usually the dirty orange one, simply because its shit.
