Cincinnati flip flop 

To change an opinion from a believable one to one that does not make sense

Jack: I used to think that the government should lower taxes because it would help economic growth. But now I think that the government should increase taxes to subsidize anti-zombie technology.

brit flop

A well meaning comeback performance destined to become a miserable failure, a flop, done by someone who used to be on top of their thing but is now failing. Refers to Britney Spears failure at the MTV Video Awards, 9/2007

She needs to rest and review her material before coming out with a new performance. She is in serious danger of doing a brit flop.

Schmekel Flop 

The sensation felt in the genital area by males when driving over rolling hills quickly.

While driving through the Appalachian Mountains we giggled about the strange feeling in our abdomen. Then my father said, "Here come more schmekel flops."

The Flop 

When you think you've hit the drop but then you need to go again in like 10 minutes.

I thought I'd hit the drop, but it turned out to be the flop. Goddamn Weetabix

belly flop 

The belly flop is a promiscous act in which the female is getting railed from behind, the male tells her that he is done, whips it out, and blows it on the bed, couch, what have you. As soon as he does so, he sticks his hands between her legs, and knocks her arms and legs out from underneath her, causing her to take a big belly flop.
