The exact origin of Box of Grease is not clearly documented, which is common for short clips that circulate through user-made soundboards and meme edits. Rather than coming with a well-known scene attached, it has survived as a standalone oddity that people recognise from repeated use in videos, streams and chats. Its appeal is not tied to one moment or fandom, so creators can drop it into unrelated jokes without needing the audience to know where it began.
