To have vigorous sex, usually with a girl, although this is not always the case upstate. A synonym of beat it up.
Since it was Valentines Day, Benny decided to surprise his wife with a romantic evening. He sent a dozen roses to her office (that is, he left them in the kitchen for her), and then sat her down to a candlelight dinner. Next he took her out for a romantic moonlit walk on the beach. To cap off the evening, he took her under the boardwalk and knocked the bottom out of it. Then when she was least expecting it, he stuck it in her dumper. Sometimes women need more from the man in their lives than just "I love you" and the occasional bouquet of flowers. Yes, sometimes they just need a fat cock up their poop chute.

Get the Knocked the Fuck out mug.
Knock the fuck out, a term used mainly when someone gets punched in the face, thereby resulting in a minor (or major) concussion or simply broken/bloody nose.
Nearly any sort of head-trauma, so long as it's very painful, is considered 'getting' knock the fuck out. You never use 'knock the fuck out' with an 'ed' at the end, because it ruins the point of the gangstuh-speak. Honestly, don't add the 'ed' or you get knock the fuck out.
Me: You better get me my weed by Monday.
John: Or what?
Me: OR YOU GET KNOCK THE FUCK OUT, THAT'S WHAT NIGGA!!
(That Monday)
Me: Bitch you got my shit?
John: No, bitch.
Me: (Punches John in the face.)
Innocent bystander: Oh shit! You just got knock the fuck out!
