Post-nut clarity is a term describing the feeling of being clear-headed or mentally "reset" after orgasm in sexual intercourse or masturbation. Feelings of disgust with oneself, as well as guilt, have also been associated with the term.
The word "nut" is found in the slang phrase busting a nut, which refers to an orgasm. The term "post-nut clarity" has been noted to be particularly used in online discussions. The term has been credited to Alexandra Cooper and Sofia Franklyn of the Call Her Daddy podcast, though the term's usage and discussion on Reddit has been documented to predate the podcast.
Media coverage of post-nut clarity often associates men with being able to anecdotally relate to having experienced it, though women have also been documented experiencing the phenomenon.
