The “senior prank” is a modern end-of-school-year tradition found mainly in the United States and increasingly in UK sixth forms. It usually involves final-year students planning a harmless joke or creative surprise during their last days at school. The idea is to leave a memorable mark before graduating and moving on.
Common pranks include filling school hallways with balloons, covering lockers in sticky notes, rearranging classroom furniture, or creating funny but harmless displays in shared spaces. While the tradition is meant to be playful, schools today often set clear rules to ensure nothing is damaged or disruptive.
Despite the restrictions, senior pranks remain popular because they give students a shared moment of fun and a sense of closure at the end of their school journey.
