Showboats, by definition, are people who show off excessively or boast about their accomplishments, skills, or possessions. Antonyms or opposite terms for showboats include modest, unassuming, humble, reserved, meek, shy, diffident, unpretentious, retiring, and bashful. Opponents also describe showboats as arrogant, egotistical, conceited, haughty, pompous, overbearing, grandiose, ostentatious, and pretentious. People who exhibit such behaviors may draw unnecessary attention to themselves, which often leads to resentment and criticism from others. As a result, it is wise to practice humility, respect, and modesty to avoid being labeled as a showboat. This will not only foster positive relationships with others but also project a positive self-image in society.
