Boasting
Boasting or bragging is speaking with excessive pride and self-satisfaction about one's achievements, possessions, or abilities.
Boasting tends to be an attempt to prove one's superiority by recounting accomplishments so that others will feel admiration or envy. It is often done by those who are socially insecure and find other people's perception of them important.
Individuals construct an image of themselves, a personal identity, and present themselves in a manner that is consistent with that image. Theodore Millon theorized that in self-presentation, individuals seek to balance boasting against discrediting themselves with excessive self-promotion or being caught blatantly misrepresenting themselves. Studies show that people often have a limited ability to perceive how their efforts at self-presentation are actually impacting their acceptance and likeability by others.
