"Bazinga" is a nonsense word that Sheldon uses to indicate that he has just successfully pulled a prank on someone. It's kind of his way of saying "Gotcha" (I fooled you).
I think that Bazinga is a word that is used when somebody plays a short prank on somebody else. Therefore, Sheldon hardly ever plays tricks. And when he does, he always says Bazinga!
