The phrase comes from online fandom culture, where shipping means supporting a romantic pairing between characters, even when that pairing is unlikely or not part of the original story. Clips like this spread through fan edits, reaction videos, and short-form posts because the line is short, instantly quotable, and easy to drop over almost any duo. It has stayed popular because it lets creators state a ship preference with humour and confidence, without needing a long explanation, and because fans enjoy using it to rally around their favourite pairings.
