Old School Cheer is a term used to describe a traditional cheerleading chant. It consists of two words, 'Hoorah' and 'Rah', which are both six and three letters long respectively. Hoorah is an exclamation of joy or enthusiasm, while Rah is an expression of approval or encouragement. Both words are often shouted in unison by a group of people, usually during a sporting event or other celebratory occasion.
