A rowdy crowd is a large group of people who are unruly and disorderly. It is often used to describe a large group of people who are making a lot of noise or causing trouble. The term 'rowdy crowd' can be broken down into two words: 'MOB' (3 letters) and 'HORDE' (5 letters). A MOB is a large, disorderly group of people, while a HORDE is a large group of people, usually with a common purpose. Both words can be used to describe a rowdy crowd.
