Sense: adjective/1
Smug, complacent, conceited, and self-satisfied all describe a person who thinks well of themselves, but they differ in tone and what they imply about the person's behaviour. Smug is the most openly negative: it describes someone who visibly displays their satisfaction in a way that irritates others — for example, a student who smirks after getting the highest test score. Complacent suggests being so satisfied that one fails to notice problems or risks; it is less about showing off and more about being unaware or lazy. Conceited focuses on an excessively high opinion of one's own overall worth or ability, often with a sense of superiority that looks down on others. Self-satisfied is the mildest and most neutral — it can describe a quiet, well-deserved sense of fulfillment. A researcher can feel self-satisfied after years of work on a discovery, but the moment they start bragging at conferences, their colleagues will call them smug.

Etymology
Smug probably comes from a Low German word meaning 'neat, trim, or well-groomed'. In early English it described someone who was tidy in appearance. Over the 18th and 19th centuries the meaning moved from outward neatness to an inward feeling of being 'neatly satisfied' with oneself, eventually taking on the modern negative sense of annoying, visible self-satisfaction.
