To be so
lazy that you won't come out of your bedroom except to eat and go to the bathroom. That would require having to stop playing video games, which would be a hassle, as you can't be AFK in your online
game or you'll risk being banned, and it's too inconvenient to back out to the lobby after a match is over because your friends might play a match without you.
Things you can't do include (but is not limited to) walking your
dog, taking out the trash, taking your laundry to the washroom, and cleaning your room to the point where you
don't even notice it smells
like a gym locker room in there.
