jumping on the bandwagon
Jumping on the bandwagon means joining others in doing something or supporting a cause that is fashionable or likely to be successful. The phrase comes from the US term for a large wagon that carried a band of musicians in a procession. It is often used in a disapproving way to criticize people who follow the crowd without thinking for themselves.
