Aggressively means doing something with forceful, determined energy, often in a way that feels pushy or intense. When a basketball player guards aggressively, they stay close to their opponent, challenge every move, and play with fierce determination. When someone argues aggressively, they push their point hard, sometimes interrupting or talking over others.

The word doesn't always mean angry or mean, though it can. A company might aggressively expand its business by opening many new stores quickly. A student might study aggressively before finals, tackling every practice problem with serious focus. In these cases, aggressively just means with extra force and intensity.

However, aggressive behavior can bother people because it may feel overwhelming or disrespectful.
