Lag Kraken
A big, stinky creature that lives in your router. It comes out whenever you play online and drags you back to the beginning like you're a loser who can't even win a game.
I was winning, then my router started screaming and I was back at the start.
I had the lead, then the Lag Kraken came out of my Wi-Fi and I got smashed.
I was about to finish the match, then my router cried and I had to start all over.
