smuglet
A smuglet is a term sometimes used informally to describe a young, smug individual. The word is a portmanteau of "smug" and "let," suggesting a diminutive or youthful version of the characteristic. It is not a formal psychological or sociological term but rather a colloquial descriptor. The perception of someone as a "smuglet" typically arises from their perceived arrogance, self-satisfaction, or an attitude of superiority that is considered out of place for their age. This can manifest in their speech, demeanor, or behavior. The term is often used with a slightly dismissive or even affectionate tone, depending on the context and the speaker's relationship with the individual being described. There is no established scientific definition or study associated with the term "smuglet." It exists primarily in informal conversation and online discourse as a descriptive label for a specific kind of youthful attitude.
