What does smug mean?
Smug describes someone who is excessively pleased with themselves, their abilities, or their position. The word often carries a critical tone: a smug person may be so confident in their own judgment that they overlook other perspectives, mistakes, or the feelings of those around them. Smug can describe a person, but it is especially natural with expressions and attitudes, as in “a smug smile,” “a smug tone,” or “to look smug.” In British and American English, it is commonly used in mildly to strongly negative contexts, especially when describing public figures, successful people who become complacent, or characters who react to others with self-important satisfaction. The related noun is “smugness,” and the adverb is “smugly.” The word is memorable because it captures a particular social attitude: confidence that has hardened into an obvious display of superiority.

Where does smug come from?
The adjective is attested from the early seventeenth century, but its deeper origin is uncertain. It is sometimes linked to “smuggle,” whose own history is generally traced to Dutch “smokkelen,” though that relationship is not secure. The words “smugly” and “smugness” were formed directly from the established English adjective.
