Highly dangerous sexual maneuver performed when a man is engaged in the doggy style position at the the edge of a balcony. Suddenly and in one motion he grabs her by both arms, climaxes, and thrusts her off the balcony full force while showering her with semen as she falls.
Since her Cincinnati Swan Dive and the damage done to the left side of her brain, Deborah cannot speak and has been eating out of a straw.
Before doing a chick, you fish one of your roommate's used condoms from the trash, turn it inside-out, and put it on. When the chick gets pregnant, you say, "It ain't mine!"
Janice thought I got her pregnant during our one night stand, but it's probably my roommate's because I gave her the ol' Cincinnati Switcheroo.
You're nailing a bitch from behind realhard, your friend (who has been hiding in the closet) jumps out, swaps with you and starts hitting it without even missing a beat. In the meantime, you run outside of the house to the window of the room that they are in, knock on the glass, and wave to her.
Shit son, you should have seen the look on that ho's face when I knocked on the window!
Cincinnati Swap!!!
Emptying your used condoms in somebody else's shoes. Typically done if the victim of the Cincinnati Shoe Shampoo interrupted a sexual act of the perpetrator or did something equally as offensive to the perpetrator.
Dude #1: "Your friend busted in on me and my girl doing the nasty so I gave him a Cincinnati Shoe Shampoo this morning."
Dude #2: "Gross dude, his feet probably smell like a protein shake now."
