Walter White is the central character of Breaking Bad, the crime drama that premiered in 2008 with Bryan Cranston in the role. Short reaction clips of the character spread widely through meme pages, edits and soundboards because his serious delivery makes even a simple exclamation feel dramatic. This waaahow became a reusable shorthand for amazement and disbelief online, detached from any single scene. It remains popular because it is brief, instantly recognisable to fans of the series, and easy to place over reveals in almost any video format.
