Banana Bread comes from SpyParty, a social deduction game built around spies completing hidden missions while trying not to be caught. The phrase has become a small piece of the game's shared language among players, and short clips like this one circulate online as in-jokes for people who recognise the reference. Because it is so brief, it is easy to reuse across edits, streams and reaction videos without needing context, which keeps it useful long after a match ends.
