Blase (or blasée, in its feminine form) is an adjective of the language French, which classifies a person's attitude skeptical, apathetic or indifferent.
This word is the verb form in the past participle of the French verb blazer, which indicates the act of becoming insensitive or indifferent. This verb derives from the verb blasen from the Dutch language, which means "to fill" or "to blow".
A blasé person may have this attitude because his senses have been weakened by excesses. It is also classified as a characteristic of a person who remains oblivious or distant from an issue when in fact they should show attention. Ex: The teachers were disappointed in him because in class he always had a blasé attitude.
An individual may show a blase attitude out of boredom, tiredness, or being snobby.
Regarding the pronunciation of this word, despite writing blase, she is pronounced as "blase", something that happens with many other French words.
It is quite common for a person with air blase being categorized as arrogant because you show no interest in the things around you and seem not to care about the opinions and interests of others.
Simmel and the attitude blase
According to the German sociologist George Simmel, the essence of blasé behavior is the indifference shown in the case of the distinction between things. Furthermore, Simmel describes the blasé individual as being "unable to react to new stimuli with adequate energy".
