May be you would better not have been asking. I can tell you the answer if you don’t be afraid to hear it.
(Probably you won’t drive your Porsche again without becoming blush for shame and you might think about of rather selling it. But not to me.)
We have a perfect term that names it well and brings the things to the point!
When we are overtaken on driving by a porsche and he speeds off my wife uses to say to me:
”E lueg doch mal, das Schnäbi!” (Hey, look at this pretty little cock)
(Whereby Schnäbi means in German “Schnäbelein” or better “Schnäbelchen” which is the diminutive of “Schnabel” and names the little pecker of a boy! The pecker ...of which is to say: the pecker is the opposite end of a cock, as if the tail of a cock is -let’s say the left end, that’s also called cock, then the pecker is the right end of a cock, what doesn’t mean that a cock has two cocks! Perhaps “pecker” is a little too big to translate “Schnäbelein”, as this might rather fit for a wren, let’s say a speckle-breasted wren, or a black-bellied wren, or may be better a bar-winged wood-wren, or even better a chestnut-banded wren, no: a happy wren! That’s it! Perhaps you prefer to look up yourself all the wrens and decide which one might fit as the best. And don’t forget to spelling the latin names as there are pheugopedius
sclateri, thyrothorus fasciathoventris, henicorhina leucoptera etcetera,etcetera ... you have to learn them all by heart!

Mind: Most important is, it has to be a very, very little bird! The most pretty little bird of all!)
But when my wife gets really very, very angry and upset about an overtaking porsche driver she is insulting and offending: “So-ne Gigu!”
(what means exactly what you are looking for!)
And now I need a cock-tail!
I think I have to stop now ere they are going to on hold my answer - calling me an “Unhold”!
