Bazinga became famous as Sheldon Cooper's catchphrase in The Big Bang Theory, where he used it after jokes and pranks, and it carried over into the prequel Young Sheldon with Iain Armitage as the younger version of the character. As clips from both shows spread on YouTube, TikTok and meme pages, the single word became shorthand that needs no setup or context. Editors still use it because the meaning is instant: someone thinks they have tricked you, and they are very proud of it.
