When people attempt to understand a new field, fail, and instead of either giving up gracefully or making a more concerted effort to understand, say, "The rules of this are stupid. Fuck that nonsense. I'm doing my own thing." and think that, somehow, their interpretation of the rules as "stupid" absolves them from having to give a shit about the rules.
I saw this recently when someone I already dislike for being heavily narcissistic took a foray into the field of music, failed to grasp why key signatures and the staff system are in place, actually misinterpreted some stuff about theory (implied that C major and A minor are the exact same thing), and then gave up and said "I'm just gonna compose what sounds good, fuck the rules, they're dumb." Sounds like sour grapes to me, just admit you didn't fucking get it
