Bravado refers to a display of bluster or exaggerated courage that may not be justified by one's actual bravery. There are several synonyms for this word that capture the same idea. One such synonym is "swagger," which suggests a confident and bold demeanor that may be more about appearances than inner strength. Another synonym is "bluster," which emphasizes the speaker's attempt to intimidate or impress others with their words rather than actions. "Pretense" or "ostentation" also convey the idea of insincere confidence or showiness. Lastly, "audacity" or "recklessness" may be used as synonyms for bravado, particularly in situations where it is accompanied by a disregard for the potential consequences.
