A "spoiler" refers to information that reveals key plot details about a story, movie, or television show, potentially ruining the experience for those who have not yet engaged with the content. Spoilers can include major twists, character deaths, or significant events that change the narrative's direction. Many fans prefer to avoid spoilers to fully enjoy the unfolding of a story, leading to the creation of "spoiler alerts." These alerts serve as warnings before discussing sensitive information, allowing individuals to choose whether to proceed with the conversation. Spoilers are common in discussions about books, films, and TV series.
