Big numbers refer to large numerical values that are often used to describe a wide range of phenomena. The term 'big numbers' can be broken down into three distinct parts: hits (4 letters), HORDES (6 letters), and BILLIONS (8 letters). Hits refer to the number of times something is accessed or viewed, such as the number of views on a YouTube video. HORDES refer to a large group of people or things, such as the HORDES of people who attend a concert. Finally, BILLIONS refer to a very large number, usually in the range of one thousand million or more.
