KNIFE-BOARD, the seat running along the roof of an omnibus.

KNIGHT, a common and ironical prefix to a man’s calling,—thus, “KNIGHT of the whip,” a coachman; “KNIGHT of the thimble,” a tailor.

KNOCK ABOUT THE BUB, to hand or pass about the drink.

KNOCK DOWN, or KNOCK ME DOWN, strong ale.

KNOCK OFF, to give over, or abandon. A saying used by workmen about dinner, or other meal times, for upwards of two centuries.

KNOCKED UP, tired, jaded, used up, done for. In the United States, amongst females, the phrase is equivalent to being enceinte, so that Englishmen often unconsciously commit themselves when amongst our Yankee cousins.

KNOCK-IN, the game of loo.

KNOCK-OUTS, or KNOCK-INS, disreputable persons who visit auction rooms and unite to buy the articles at their own prices. One of their number is instructed to buy for the rest, and after a few small bids as blinds to the auctioneer and bystanders, the lot is knocked down to the KNOCK-OUT bidders, at a nominal price—the competition to result from an auction being thus frustrated and set aside. At the conclusion of the sale the goods are paid for, and carried to some neighbouring public house, where they are re-sold or KNOCKED-OUT, and the difference between the first purchase and the second—or tap-room KNOCK-OUT—is divided amongst the gang. As generally happens with ill-gotten gains, the money soon finds its way to the landlord’s pocket, and the KNOCK-OUT is rewarded with a red nose or a bloated face. Cunning tradesmen join the KNOCK-OUTS when an opportunity for money making presents itself. The lowest description of KNOCK-OUTS, fellows with more tongue than capital, are termed [BABES],—which see.

KNOCKING-SHOP, a brothel, or disreputable house frequented by prostitutes.

KNOWING, a slang term for sharpness; “KNOWING codger,” or “a KNOWING blade,” one who can take you in, or cheat you, in any transaction you may have with him. It implies also deep cunning and foresight, and generally signifies dishonesty.
