"[jump|climb|get] on the bandwagon" Meghatározása és Jelentése

What is the origin of the idiom "jump on the bandwagon" and when to use it?

The origin of the idiom "jump on the bandwagon" can be traced back to the mid-19th century in the United States, particularly from the practice of political campaigns using a bandwagon, a large wagon or float, to transport the candidate and their supporters during parades and rallies. As the bandwagon rolled through the streets, it would attract attention and gather more people who wanted to be associated with the popular candidate. It is used to describe situations in popular culture, such as when individuals show sudden interest in a particular music artist, fashion trend, or social media challenge simply because it is widely embraced.
