Coub

A person in a yellow hoodie and blue jeans is sitting at a desk in a classroom, repeatedly leaning forward and resting their head on the desk surface. The motion is a continuous, rhythmic lowering of the head onto the desk, with the person's upper body moving down and then slightly lifting before repeating the motion. The setting is a classroom with rows of desks and chairs, a light blue wall, and a blackboard in the background.
