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.

Get the Cailloumug. 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.
