NOT First used on the 'Family Guy'!... the previous definition of 'Gigadity gigadity' is accurate however these words were not first uttered by Quagmire. They were used previously in the Movie 'Can't Hardly Wait' 1998 (pre-dating Family Guy) by the actor Breckin Meyer portraying 'Walter' the band leader at this fucked up party. Seth Green (who we all know does several voices and has a lot of creative input in Family Guy) also stars in this movie.
"and then I did your girlfriend!---Gigady Gigady!" (I don't actually remember the fucken exact words... steal the movie and see for your fricken self tough guy!)
The cataclysmic death of a billion people or more. This is equivalent to one thousand megadeaths. This does not need to occur in a single event, but from a connected cause. This word was derived from "megadeath", which was coined in 1953 to describe the results of nuclear war. In contrast, "gigadeath" was coined to describe the more massive catastrophe of industrial civilization combined with peak oil, global warming, ecological degradation, and explosive population growth overshooting the global carrying capacity.
"Abrupt climate change would inevitably lead to gigadeath."
"Humans can live sustainably on this planet, but only after a few gigadeaths."
A unit of measuring data size. It is either 1,000,000,000 or 1024 megabytes, depending on how your computer reads it. A DVD can handle 4.7 gigabytes. A blu-ray disc can handle 25.
Basically, the more gigabytes your hard drive can take, the more porn you can shove on it.
