An offshoot of the onomatopoeic
word "boing," the phrase "Sha-Boing BOING!" is used as a confident emphasis at the end of an assuredly correct statement. This is similar to other phrases such as "Yeah, that's RIGHT!," "That's what I'
m sayin'," "You said it," or (in more spiritual settings) "Can I get an Amen?"
Emphasis is put on the second "boing" and the gusto with which that "boing" is delivered is meant to underscore the sincerity of the speaker'
s resolve that his/her statement is the undeniable
truth.
This phrase is especially useful after successfully completing an act which others have claimed
impossible.
