A surprise party is a celebration organized to surprise a person, typically for a special occasion like a birthday or an anniversary. Friends and family plan the event secretly, ensuring the guest of honor remains unaware until the moment of the surprise. Decorations, food, and activities are often arranged in advance to create a festive atmosphere. Guests usually gather at a designated location before the guest of honor arrives. When the person enters, everyone shouts "Surprise!" to reveal the celebration. This type of party aims to create joyful memories and strengthen relationships among those involved, making it a cherished experience for everyone, especially the honoree.
