shmuck
⇨ shmuck; schmuck
1. noun
1
a fool; an objectionable person. Taken into general usage from Yiddish; the literal meaning is 'penis', hence the original Yiddish usage in this sense had a particularly derogatory tone. The variant 'schmuck' seems to have been adopted in error due to a similarity in sound to Yiddish schmuck (jewel) UK, 1892.
