The 'Dear Diary...' meme format is a long-standing internet staple used to frame personal confessions, daily struggles, or dramatic irony in the style of a private journal entry. While it doesn't originate from a single source, it often features characters—ranging from grumpy cartoon figures like Squidward Tentacles to pensive animals—appearing to write down their thoughts. The humor typically stems from the juxtaposition between the formal 'Dear Diary' greeting and a chaotic, overly dramatic, or painfully relatable revelation that follows. It has evolved into a versatile storytelling tool for social media users to highlight the absurdity of modern life, social anxiety, and the humor found in minor personal failures.
