Bazinga
Bazinga is a catchphrase from CBS sitcom The Big Bang Theory, said by physicist Sheldon Cooper after pulling a prank on his friends. First aired in May 2009, it later fueled an ironic 4chan and Tumblr parody scene mocking the show's brand of geek humor.
Overview
Bazinga is a nonsense interjection used like "zing" or "gotcha," which Urban Dictionary contributors define as a catchy phrase to accompany a clever prank4. On CBS sitcom The Big Bang Theory, theoretical physicist Sheldon Cooper (played by Jim Parsons) yells it after tricking a friend or landing a joke1. The word sounds vaguely scientific because it stitches together the chemical symbols for Barium (Ba), a fictional element Zuunium (Z) from the in-show Timber Wolf comics, Iodine (I), Nitrogen (N), and Gallium (Ga)3.
Two very different fandoms grew around the line. Fans of the show wore it on t-shirts and mugs sold at pop-culture retailer Hot Topic5. An anti-fandom on 4chan and Tumblr turned bazinga into shorthand for what they saw as the show's cheap, over-explained geek humor, spawning a wave of deliberately unfunny parody comics5.
