What does schoolboyish mean?
Schoolboyish describes behaviour that seems immature, childish, or excessively youthful for an adult. The expression often points to impatience, emotional overreacting, dependence on approval, or enthusiasm for something trivial, although it can also be used affectionately for a display of youthful energy. For example, someone might describe a colleague's schoolboyish excitement about a minor victory as charming or mildly embarrassing, depending on the context. Its force comes from the contrast between a grown-up person's conduct and the behaviour traditionally associated with schoolboys. The word is informal and usually mildly disapproving, but it can carry a playful or nostalgic tone rather than expressing serious condemnation. It is less common than the broader terms childish or immature because it identifies a specific kind of youthful behaviour.
