"Mensch" a 1x3.25in Vinyl Sticker. A mensch is "someone to admire and emulate, someone of noble character. The key to being 'a real mensch' is nothing less than character, rectitude, dignity, a sense of what is right, responsible, decorous." The term is used as a high compliment, implying the rarity and value of that individual's qualities. In Yiddish, mentsh roughly means "a good person". The word has migrated as a loanword into American English, where a "mensch" is a particularly good person, similar to a "stand-up guy", a person with the qualities one would hope for in a friend or trusted colleague.
