Gen 5 Camaro Internal Engine Tech - Where does this ---> "dumdumdumdum" come from?

I keep seeing this popping up in a lot of threads about the new Camaro. Can someone clue an idiot in on this please?

It's for the tools that call a Camaro a "M-a-r-o".

it comes up with other words also.

ha, I remember it was in that South Park episode about the Mormons... basically saying that that religion is dumb....

dumdumdum= f-t-w
dumdumdumdum= s-r-t-4

dum dum dum...is a spawn of satan for those of us who type with long drawn out (glorious) Southern Twangs. Camaro has too many syllables to write..M@RO is much easier for those of us that type with a slow twang :p

Singers: Martin went home to his wife
Dumb dumb dumb dumb dumb
And showed her pages from the Book of Mormon
Dumb dumb dumb dumb dumb

Harris: A-and so Joseph Smith put his head into a hat, a-and read to me what the golden plates said. I wrote it all down and we're gonna publish it into a book.

Mrs. Harris: Martin, how do you know he isn't just making stuff up and pretending he's translating off golden plates?

Singers: Lucy Harris smart smart smart
Smart smart smart smart smart

Well another version that is similar is "dum-da-dum-dum....dum-da-dum-dum-dummmmmm" which of course if from the original TV series Dragnet :D
