Pretty basic question. I’m not looking for anything very specific. Just things that might make you cock an eyebrow when talking to someone.
When someone dismisses something solely because it’s mainstream or popular.
When someone enjoys something esoteric, and looks down upon those who don’t have the same appreciation or understanding it. The stereotypical example here is the snobby wine-lover.
Unnecessary use of foreign phrases and pronounciations when ordinary ones exist in English. An example would be the person who insists on ordering pastas with the full Italian accent.
