What is a mischievous trick?

A mischievous trick is a playful or sly act intended to cause surprise, amusement, or mild trouble for someone. It often involves a clever or cunning plan, such as pranks or jokes that can lead to laughter or lighthearted annoyance. While typically harmless, these tricks can sometimes test the limits of good-natured fun, depending on the context and the reactions of those involved.
