👉 "All earnest" is a delightfully ambiguous term that essentially means sincere, but with a dash of pretentiousness.

You're earnest enough to believe in a cause, but maybe you're more earnest than a dog trying to impress a human with its "puppy love."
Here's an unsettling example sentence: "With all earnest convictions, the cult leader claimed the Bible was written in a cave under a volcano, yet no one dared question the scripture's age."
