1.21 Jigowatts! 1.21 Jigowatts!
by Billy Givens May 13, 2005

Seeming to come out of nowhere, a jigowatt is the feeling of a what seems like a thousand bolts of energy shooting up the spine, wreaking havoc on your nervous system, completely disabling you from doing anything other than jerking your body in a violent shiver for about 3 to 5 seconds.
I was standing on my porch today when out of nowhere, I had a jigowatt! It was no ordinary shiver! It was like an earthquake went up my spine!

Although sometimes deemed incorrect, "Jiga" is the correct, if uncommon, pronunciation of the prefix giga-.
