John S. Farmer, Slang and its analogues past and present…
“ Grose, Vulg. Tongue, s.v. A word of various imports, according to the place where it is spoken; in the city it means a rich man; at Hockley in the Hole, or St. Giles’s, an expert boxer; at a bagnio in Covent Garden, a vigorous fornicator; at an alehouse or tavern, one who loves his pot or bottle: and sometimes, though but rarely, a virtuous man. ”
