Bill Wurtz released History of Japan on YouTube in 2016, condensing thousands of years into nine minutes of fast narration, jingles, and visual gags. The video went viral for making dense history feel light and quotable, and short lines from it were clipped for soundboards and edits. This phrase became a reusable shorthand for alliances and expanding friend groups, detached from its original timeline context. Its lasting appeal is the contrast between a huge historical subject and a narrator who explains coalitions in the simplest possible words.
