In the video, a man is sitting in the back seat of a car, wearing a black shirt and glasses. He is holding onto the back of the front seat with one hand and using the other hand to make a fist. The man then proceeds to tap his knuckles on the back of the seat, creating a rhythmic sound. He continues to tap his knuckles on the seat in a steady beat, maintaining a consistent rhythm throughout the video. The man's facial expression is neutral, and he appears to be focused on the sound he is creating. The car is stationary, and there are no other visible objects or people in the video.
