Not Big Surprise is a voice line from Heavy, one of the playable classes in Valve's team-based shooter Team Fortress 2, first released in 2007. Heavy, voiced as a stoic Russian heavy weapons specialist, has a large set of in-game taunts and responses that players quickly clipped and shared outside matches. The line spread through soundboards, gaming montages and meme edits because its sarcastic understatement fits almost any predictable outcome. Years after release, it remains popular as a quick reaction sound for creators who want a dry, instantly recognisable punchline without explaining the joke.
