A fake or a copy of someone or something. Chinatown has some of the best knock-off bags, shades, etc. Chinatown is considered Lil China located in Manhattan. The word knock-off basically means fake. So put two and two together. A Chinatown Knock-off is something or someone who's fake.

Get the Knock jointsmug. 
To smack, slap or impede in any way the act of a sexual groping, especially from an annoying boyfriend who just wants to grab a titty or a cheek for grabbin's sake (because that's his ass to grab). This definition is reversible for male-to-female, except most men will opt out of the knock away and allow the grope in almost any instance.
