Bazinga became Sheldon Cooper's catchphrase on the CBS sitcom The Big Bang Theory, which ran from 2007 to 2019. Played by Jim Parsons, Sheldon used the word after practical jokes and moments of triumph, helping it spread far beyond the show into everyday internet slang. Clips of the line were shared on early meme pages and soundboards, then reused in short form edits and reaction videos. Its mix of geek culture and smug humour keeps it recognisable to both TV fans and meme audiences today.
