Object in negative six games??

As of right now, the Covenant Destroyer Class is associated with -6 games... I wonder if it'll stay that way if someone adds a game or two or if it'll reset to the correct number... Anybody know what games this relates to?

Since it's a negative number, it must be in 6 of whatever the opposite of games are. I suggest looking for that in:

Homework
Jack Thompson
Liver and lima beans
Romance novels
Those little dogs that yap all the time
That ex- boyfriend or girlfriend you had that hated video games
Pancreatic cancer
etc.
