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.
Male: why do you keep blocking me?
Female: I didn't block you, I did the knock away.
a fetish where the deliverer holds the recipient on their lap, with the recipients feet over their head. the recipient then proceeds to knock the deliverers head down to the ass of the recipient. For added pleasure you may add a buttercream pie on top of that ass, or the deliverer may put on a beak to resemble a bird, also known as patty flocking.
Guy 1: "Damn, that chicks lookin good."
Guy 2:" I'd patty-knock that bitch up."
Any of several well-known "door-tap pun" verbal exchanges which involve either an offer ("Howard", "Tijuana", etc.) or a request ("Woodrow", "Kudu", etc.) by da speaker to da listener; often, said query is proffered in said manner in an effort to lighten da mood and add a little humor to said proposal, in order to hopefully take some of da sting outta da expressed idea, which might involve less-than-desirable aspects such as difficult/yucky/tedious labor, significant changes in habits/lifestyle such as being more active and/or giving up "comfort" foods, etc.
A lot of da utility knock-knock joke selections are somewhat "interchangeable" as far as their "request" or "offer" status --- i.e., a word dat's mostly intended for proposing an assistive/generosity action by da speaker to da listener (such as "Howard you like me to _?", or "Tijnana do/have _?") can also be used by da speaker for asking for assistance/charity from da listener (such as, "Howard you feel about doing _?", or "Tijuana volunteer to _?"). Or by da same token, a gigglingly-uttered conversing dat uses a word which is usually reserved for giving-of-time/resources appeals can also be used by da speaker to extend an offer of help to da listener, such as, "Woodrow like me to _?", or "Kudu let me help you out by _?"
