The phrase itself has long been used as a simple way to promise remembrance between close friends, and as a short audio clip it fits naturally into the online language of farewells and tributes. Creators reuse it because it is instantly understandable without context, needing no setup to signal loyalty, loss or gratitude. Its nine-second length makes it easy to drop at the end of an edit, where a single spoken line can close a story more effectively than a longer speech, which is why it keeps appearing in friendship, gaming and fan-made farewell videos.
