"Goody-two-shoes" is a term used to describe someone who is overly righteous or acutely moralistic. Synonyms for this phrase include "holier-than-thou," "sanctimonious," "priggish," "puritanical," "smug," "pious," and "self-righteous." These words refer to someone who appears to be insufferably moral and righteous, often with a hint of hypocrisy. Other synonyms include "saintly," "virtuous," "morally upright," and "pietistic." While these adjectives can be positive in certain contexts, when used to describe someone as a "goody-two-shoes," they can come across as slightly negative or critical. Ultimately, the term suggests a smug, self-righteous individual who can often be disingenuous in their displays of virtue.
