When a person is talking about a certain famous act (such as a band), and another follower in the conversation decides to say that he/she likes them, yet they can only name their most notable work because they hear it as often as everybody else because. This is usually carried out because they want to appeal to or impress their target of interest.
Person 1: dude i love muse they're so awesome
Person 2: same here
Person 1: can you name two songs by them besides uprising and resistance
Person 2: nope
Person 1: wow what a subject wannabe...
