Shmendrik

Shmendrik (Yiddish: שמענדריק), also rendered as schmendrick or shmendrick is a Yiddish word meaning a stupid person or a little hapless jerk ("a pathetic sad sack"[1]).

Its origin is the name of a clueless mama's boy played by Sigmund Mogulesko in an 1877 comedy Shmendrik, oder di komishe Chaseneh (Schmendrik or The Comical Wedding) by Abraham Goldfaden.

[2][3] The play was inspired by a sketch presented by Mogulesco at an audition before Goldfaden.

Regarding the perception of the word, The Joys of Yiddish lexicon stresses the meagerness of shmendrick compared to other Jewish schm-words for luckless persons: "A shmendrik is a small, short, weak, thin, a young nebekh".

This is directly opposite to mentsh (more commonly spelled as "mensch") which, in short, means a "real" man of upstanding character and a person to emulate.
