Kareoke Night

A man in a white t-shirt and black shorts with a green stripe stands in a room with beige walls, holding a knife in his right hand. He repeatedly swings the knife in a horizontal arc across his body, moving from left to right, while keeping his head down and his body slightly hunched. The motion is continuous and rhythmic, with his left arm swinging in opposition to his right arm's movement. The background remains static, showing a wall with a plant and a decorative item.
