A boxed-in face with shouting open mouth. The square brackets [ and ] frame the face like a tight border — kaomoji sometimes use brackets instead of parens to suggest rigidity or contained energy. Inside, ○ circles on each cheek puff up with anger, ` and ´ accent strokes point inward as furious eyebrows, ･ small eyes, and Д (Cyrillic capital De) is a wide, square open mouth — the classic ‘shouting’ shape.
The box frame is the visual hook. Most kaomoji use rounded parentheses; this one’s hard corners give the face a ‘this person is barely containing themselves’ feel. It is angry, but the brackets keep the anger from spilling out — closer to suppressed irritation that has reached its limit than to total meltdown.
Use it for situations where you are publicly fed up but trying to keep it together — venting in a Discord channel about your project, complaining about a bad client, reacting to a long-running annoyance. On Twitter/X it works for short rant tweets. Because the frame makes it feel slightly tense, it lands better in ‘I am tired of this’ contexts than in pure fun-anger ones.
The matching Japanese expression is もうがまんできない (mou gaman dekinai — ‘I can’t take it anymore’). Pair with words like ふざけるな (‘fuzakeru na’ — ‘don’t mess with me’) or いいかげんにしろ (‘ii kagen ni shiro’ — ‘cut it out already’).
