When you're playing Card Jitsu in Club Penguin and your opponent's penguin is purple and also has a purple belt. It is an incredibly dangerous combination, and you will most likely lose your match if your opponent is sporting this look.
Person 1: Dang man, she just got a purple belt, and changed her colour to purple.
Person 2: You know how the saying goes dawg... Double Purple Means Trouble!
