Origin of the Yiddish term 'Chunyuk'
Many of you may be familiar with the Yiddish word 'Chunyuk' literally a super religious fanatic but are unaware of the origin of the term.
Some time ago I came across a small booklet entitled Yiddish; the holy language by Rabbi David Cohen, Rabbi of Congregation Gvul Yaabetz in Brooklyn, NY. The book contains a listing of Yiddish terms and expressions and highlights their origins. According to the Sefer the origins of the term Chunyuk are as follows (translation mine):
During the early years of the Second temple period, Shimon Hatzadik (Simon the Just) officiated as the High Priest (which was at the time the most senior political and religious Jewish leader). Shortly before his death he bequeathed his position to his younger son Chonyo instead of his older son Shimi. Shimi was overcome with jealousy and decided to play a cruel trick on his younger brother. On the day that he was to enter the Temple to perform the sacrifices, Shimi called to his brother and told him that he wanted to assist him in doing the rituals properly. He then proceeded to dress him up in women's clothing and when Chonyo ascended the altar, those present became enraged at this perceived sacrilege and sought to kill him. Chonyo eventually fled to Egypt where he built the famed "Mikdash Chonyo"  .
