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

A 4 year old devils spawn from Canada. When it doesn’t get its way, it throws a cancerous tantrum that can blow the eardrums of even deaf people. The brat even got its own T.V. Show to spread the cancer that he is unto innocent children and depressed single mothers. Thankfully PBS canceled the shit hole of a show saving MILLIONS of innocent lives. This may be proof that god actually exists.
Doctor: we just got the diagnosis in, you have a tumor in your brain. When did you start getting your first symptoms?
Mother: I started noticing after I showed my kid Caillou.
Doctor: makes sense.

Insult used to describe an autistic manchild riddled with cancer who cannot live without their parents. One of the worst slurs you can call a person, the N Word to humanity.
“Bro, you need to move out of the house, you’re being a total Caillou right now.”

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.
