Lerping 

(v.) Walking unnaturally, with the right arm swinging forward simultaneously as the right leg bears weight, repeating with the left arm and leg and so on. This normally occurs during stressful moments when someone is nervous and asked to walk in front of an audience of their peers. The individual will overthink the task and lerp.

John was asked to briskly walk across the stage to the rhythm of the music when he started lerping. That’s when everyone began to laugh.
