A stock phrase used after the hero has done some derring-do that obviously was very painful and/or taxing. In saying this, the Hero is acknowledging that he is not open to repeating the experience as he tries to recover.
It's a form of Lampshade Hanging to the kind of exaggerated heroics often displayed in action shows. Can also be used tongue-in-cheek in response to a particularly absurd suggestion.
Contrast with Wasn't That Fun?.
Not to be confused with We Are Not Going Through That Again, where a character refuses a new quest, not just a particular feat, or May It Never Happen Again, for when people outright try to ensure that it won't happen again. See also Let Us Never Speak of This Again, which is often paired with this.
