An unruly crowd is a large group of people who are disorderly and difficult to control. The term can be broken down into three words: MOB (3 letters), RABBLE (6 letters), and HORDE (5 letters). A MOB is a large, often angry, crowd of people. A RABBLE is a disorderly crowd of people, usually with a common purpose. Finally, a HORDE is a large group of people, often with a shared goal. All three terms describe an unruly crowd, which is a large group of people who are difficult to control due to their disorderly behavior.
