goody two shoes

Etymology
From. Generally considered to have originated with the title character in  (1765), which indeed seems to be the source of its later use as a common noun with the present meaning. However, as a proper noun with implications of wealth rather than goodness, it is also found earlier, c. 1687, in the writings of : “Why, what then; Goody Two-Shoes, what if it be? / Hold you, if you can, your tittle-tattle, quoth he.”

Noun

 * 1)  A goody-goody; a person who is exceptionally good and perhaps self-satisfied.
