Koettke mentions Francis Grose’s Dictionary in the Vulgar Tongue published in 1811. A few samples:
FLOGGING CULLY. A debilitated lecher, commonly an old one.
COLD PIG. To give cold pig is a punishment inflicted on sluggards who lie too long in bed: it consists in pulling off all the bed clothes from them, and throwing cold water upon them.
TWIDDLE POOP. An effeminate looking fellow.
ROUND ROBIN. A mode of signing remonstrances practised by sailors on board the king’s ships, wherein their names are written in a circle, so that it cannot be discovered who first signed it, or was, in other words, the ringleader.
