jagged

This term evokes a tactile sense of danger or discomfort, suggesting edges that could cut or snag. It is frequently used to describe natural geological formations or broken materials like glass and metal, where the irregularity is unplanned and harsh. When applied to visual data or lines, it describes a lack of smoothness, implying a series of abrupt, sharp changes. This creates a feeling of instability or volatility, such as in a fluctuating stock market graph or a distressed electronic signal.
