The 'I Thlammed My Penith in the Car Door' meme originated from a viral voice-over parody featuring a character resembling Daffy Duck experiencing a painful and absurd accident. The humor is driven by the character's exaggerated lisp and the soul-piercing scream that follows the titular line. First gaining popularity on Twitter and YouTube, the phrase became a shorthand for sudden, self-inflicted misfortune. It is frequently used in shitposting circles and TikTok edits, often paired with high-contrast visuals or distorted audio to emphasize the chaotic and slapstick nature of the original soundbite.
