Zitering refers to the phenomenon where a person, often a child, experiences a sudden, uncontrollable burst of energy and excitement, often leading to hyperactive behavior. This can manifest as rapid movements, high vocal energy, and a general inability to settle down. It is typically temporary and can be triggered by various factors such as sugar intake, overstimulation, or emotional highs. While not a formal psychological term, it captures a recognizable and relatable experience for many.
