Klutter!

Klutter! is an informal, expressive interjection used to convey a sense of overwhelming chaos, disarray, or general messiness. It is often used as a reaction to discovering a particularly untidy or disorganized space or situation. The exclamation can also be used to describe a feeling of mental disarray or confusion.

The term is generally considered to be a humorous and exaggerated reaction rather than a serious assessment. It lacks a formal definition and relies primarily on contextual understanding. Similar interjections might include "Yikes!", "What a mess!", or "Oh, dear!". The precise meaning and tone can vary depending on the speaker's intonation and facial expression.

Klutter! is rarely used in formal writing or speech, being more commonly found in casual conversation, informal writing such as blog posts or social media, and particularly in contexts aiming for comedic effect. Its usage is primarily descriptive of the user's subjective experience of disorder.
