indeed, I'm personally fond of using it to disparage things I don't like.

It's a most excellent insult.

You get the implied snobbery of an upper-class person looking down on their inferiors, whilst also maintaining some street cred via not insulting the painfully poor.

examples: "stupid middle class French boys" "god-awful, self-indulgent prose that only the most basic of middle-class housewives could appreciate" "a speech reeking of vapid middle-class cliches" ...
