Every word can be an insult if said with the intention of hurting and/or making fun of someone, and even the biggest slur doesn't need to be taken as an insult in the appropiate contexts.
Of course, you jokingly say something to someone and not really mean.
But I'm talking about when someone means what they say. Because calling someone a normie without irony means you consider them lesser because they enjoy popular things. It's more the superiority complex part that that annoys me than anything else.
