A bald child in a Canadian television show, which thank god got cancelled. Caillou bullies other children, physically harms his parents, and probably swore in a deleted episode. Caillou is a great example for children of all ages! Watch Caillou today! (Wait it is deleted)
Mom: Caillou, time for dinner!
Caillou: The heck it isn’t idiot. I’m play with my dinos, now do die in a hole.

Get the Caillou catmug. A tortured child whose parents refuse him everything he asks for just to watch him cry and suffer psychologically, and to then give him a tiny bit of what he asked for just to calm him down and regain his trust without complying to his initial demand, feeling superior, and be able to repeat the cycle of abuse.

Get the Cailloumug. It means bald, because Caillou is bald. If you are talking to a weeaboo/japanophile, you can say Saitama-flavored, because of the famous bald anime character, saitama from One Punch Man
