(a) A jabberjay is a genetic mutation from the series The Hunger Games by Suzanne
Collins, used for the war during The Dark Days (the rebellion of the people against the
government). After the war, they bred with mockingbirds to produce mockingjays.
(b) A "Jabberjay" is also what die-hard and totally
obsessed fans of aforementioned series call themselves.
The jabberjays could memorize long passages of the District people's plans - but eventually, the District people started feeding the Jabberjays lies, making them utterly
useless.
I got Mockingjay the first day it came out and
red it in thirty minutes
flat. I am such a total jabberjay.
