Remark accompanied by a facepalm

IMAMORON

Think of a self-deprecating text shorthand that starts with "I'm a..." and ends with frustration.

The clue plays on the phrase "I am a moron," which is something you might mutter in frustration when doing something foolish—often paired with a facepalm. The answer "IMAMORON" blends the confession ("I am a moron") into a single word, making it a self-deprecating joke. It’s a common internet shorthand for that moment of realization when you’ve done something silly.
