Definition & Meaning of "apeshit"in English

What is the origin of the term "apeshit" and how is it used?

"apeshit" is a slang term that emerged in American English in the mid-20th century, originally describing extreme, uncontrolled behavior, often anger or frenzy, by comparing it to the perceived wildness of apes. Over time, in informal and especially youth or music culture, the term developed a positive sense, meaning extremely intense or impressive—e.g., doing something extremely well or with full energy. It is used in casual speech, entertainment, and social media. The term is vulgar due to its origin in "shit," but in this context it emphasizes intensity rather than offense.
