@panzade,
No it ain't. Quackenrush is just too clever by half. It does not convey the impression of a frightened duck. And ducks only move rapidly when they are frightened. As do all the organisms mentioned in Charles Darwin's masterpiece.
Which gives evolutionists a bit of a problem with Olympic gold medal winners as it is not easy to admire frightened organisms.
Evading the difficulty by declaring that I am pissed is a technique educationally disadvantaged people use. Often as a habit.
