Gigaparsec 

Is a measurement of distance. More so, is the largest measurement of distance there is. The reason for this is because the approximate radius of the entire observable universe is just 14 gigaparsecs.

The equivalent distance in meters is 3.3 x 10^25 meters, which could also be written as:
330,000,000,000,000,000,000,000,000 meters.
(Three-hundred and thirty septillion meters)

OR 3.3 billion light-years.

Brian- "Haha, my penis is a gigaparsec long."

Mark- "So, you're saying your penis is 2,429,669,490,000,000,000 times larger than the diameter of the earth itself?"

Brian- "Yeah, that sounds about right."

Mark- "Hm, seems legit."

gigapause 

The Gigapause was an extensive period of time, lasting for nearly a year, when the creator of Homestuck (Andrew Hussie) took some time off of posting updates for the popular webcomic. During that time, Homestucks barely clung to life as they awaited more updates. When the Gigaunpaused was released, MS Paint Adventures crashed, and multiple bugs showed up, all because so many Homestucks logged on all at once.

Non-informed person: "I heard that that person reads something called Homestuck... What is that?"
Person in their right mind: "Go ahead and ask them, but do NOT mention the word 'Gigapause' if you want to live."
