The term bandwagon is commonly used to ridicule a person for only liking something because it is mainstream or successful.

For example, a hardcore Star Wars fan might say that people are just now hopping on the Yoda bandwagon.

Bandwagon is also used in sports to accuse “die-hard fans” of supporting whichever team is currently playing the best.
