A term for methusalem-aged stiff, white-haired toothless and nearly blind dogs, mainly German Shepards and German Dachshounds, always expressed in 3rd person (he instead of you) with a warm friendly voice of rapture patting the dogs head with emphasis when their Feiner successfully shat, brought a stick, tore a blanket or bit someone.
It's pronounced as 'finer'.
The opposite of a Feiner is a "Pfuihund" (filthy dog).
The target of a Feiner, eg. food, a pillow or pants is called a "Feini" (fine thing, pronounced: finy).
So ein Feiner ist er, ja, er ist so ein Feiner (Such a fine one he is, yes, he is such a fine one)
A man who is literally the finer of men. A large penis and long hanging testicles make him more of a horse than man, however his sense of humor and witty banter effectively make him a great man. His one liners and puns mixed with his ability to get any girl can produce instant orgasms among ladies simply by walking by.
(Girl) Holy crap, I just orgasmed, that must've been a feinerman!!!
