'Boatsex' is a term popularized by the Game of Thrones fan community, specifically on Reddit's r/freefolk, to describe the long-awaited romantic encounter between Jon Snow and Daenerys Targaryen in the Season 7 finale. The term became a viral prophecy among 'shippers' who had predicted the union for years. However, the meme took on a humorous and awkward layer because the scene was intercut with Bran Stark’s narration revealing that Jon is actually Daenerys's nephew. Today, the meme is used to discuss the show’s controversial ending, fan expectations, and the classic 'bittersweet' nature of George R.R. Martin's universe.
