Commonly used terms in the Electrical industry.
ground bounce noise
ground bounce occurs when a large number of semiconductor circuit components are mounted on a
common semiconductor chip substrate, so that they are imperfectly insulated from each other. In normal operation the substrate should act as an insulator; however, during certain unusual fluctuations in signal levels, the systems power and ground connections can experience fluctuations, which affect the performance of each component in a random way that has the characteristics of noise, much like capacitive coupling.
