A joke about the heavy founder of Valve, Gabe Newell, a
game developer that creates great games but is terribly slow. (See Valve Time) It stems from Gabe himself saying that a certain
game will be "Worth the wait" when it comes out.
It created a
Youtube craze, just look it up on there.
Person
1: Half-Life 3 is taking an awfully long time to be released, and Gabe has no
news...
Person 2: Hopefully it will be worth the
weight!
