Disagree with the assertion that use of the word ‘fanboy’ is without exception cliched. A cliche may be invoked inappropriately, but it almost always only comes into being because it accurately describes a certain sort of thing that really exists.
As to the use of cliches as a way to insult others and shut down conversations, I am of the view that some people invite insult by their actions or words, and some conversations are better shut down.
