BAZINGA – (spelled "Buzzinga" in the subtitles of DVD releases) is a catchy phrase to accompany your clever pranks (Urbandictionary, 2009). This word has been popularised by Sheldon Cooper in The Big Bang Theory TV show.
Sheldon's ability to surprise and irritate people with jokes stems from his apparent inability to recognize sarcasm and his inability to recognize when he is being too harsh in certain situations. This leads to assumption that Sheldon will always be blunt or harsh, but because of this assumption, he is able to easily interject crude pranks or jokes into conversations.
Below is the video with Every Bazinga Moment from The Big Bang Theory (seasons 1 to 4).
