excessive self-interest or admiration
narcissism - arrogance
If you have an excessive love for yourself, or are preoccupied with your appearance and own interests, then you might be accused of ‘narcissism'. Taken to an extreme it can be classified as a mental illness, but in everyday life, the term is typically used to refer to a vain, selfish man who puts his own well being above that of anybody else. Such arrogant behaviour usually elicits a negative response from others.
