Prolonged spats are often referred to as FEUDS. FEUDS are disagreements or conflicts that last for a long period of time, sometimes even generations. They can be between two people, two groups, or two countries. FEUDS can be caused by a variety of issues such as jealousy, revenge, or power struggles. They can also be caused by misunderstandings or miscommunications. In some cases, FEUDS can become so intense that they lead to violence or even death.
