Schmuck or shmuck in American English is a pejorative meaning one who is stupid or foolish; or an obnoxious, contemptible or detestable person. The word entered English from Yiddish (‏שמאָק, shmok), where it has similar pejorative meanings, but its original meaning in Yiddish is penis.[1][2] Because of its vulgarity,[3] the word is euphemized as schmoe, which was the source of Al Capp’s cartoon strip creature the shmoo.[4] Variants include schmo and shmo.
