👉 Rudimentary (a pun on "underdramatic") is an expression that refers to something trivial or mundane. Imagine a person who's completely clueless about the intricacies of modern technology but still thinks they're smart.
Example sentence: "I'm so rudimentary that I don't even know what 'up()' means." This expression can make you cringe, as it suggests total ignorance and unadorned stupidity.
