The phrasal verb "brush off" is predominantly used in informal contexts and carries a dismissive connotation, often referring to ignoring or casually dismissing someone or something without giving it serious attention. This term is commonly used in everyday conversation to describe interactions where someone chooses not to engage in a discussion or downplays concerns and is less frequent in formal writing or speech. For example, one might "brush off" a compliment or "brush off" a suggestion they do not take seriously. It can also be employed in contexts involving ignoring social overtures or criticism. It reflects a kind of nonchalant attitude in the interaction dynamics, underscoring the actor’s choice to bypass engagement. The verb can also be used literally to mean removing dust or dirt from a surface, albeit less frequently compared to its idiomatic usage.
