Alrightnik - One who has succeeded (fem. alrightnikeh)

From Leo Rosten's Joy of Yiddish:
-nik, or -nick (Pronounced "NICK": a suffix from the Slavic languages)
This multipurpose syllable converts a verb, noun or adjective into a word for an ardent practitioner, believer, lover, cultist or devotee of something. Thus, a nudnik is someone who nudzhes or pesters. An alrightnik is someone who has done so well that he is prosperous. We are all familiar, of course, with beatnik and peacenik. The New York Times recently referred to Bachniks, and a friend of mine, dieting, wailed that it was especially hard for her because at heart she was a noshnik.
-Nik lends itself to delightful ad hoc inventions. A sicknik would be one who fancies sick or black humor. A Freudnik would be an uncritical acolyte of the father of psycholanalysis. And recently homosexuals have begun to refer to heterosexuals, with some amusement, as straightniks.
