A spoiled brat.

Oh, that's Timmy. He is such a Caillou.

pull a Caillou 

to act like an ungrateful, spoiled whiny douchebag who gets upset on first world problems, just like those spoiled rich kids you see on snapchat and spoiled brat tantrums cringe compilations, or simply misbehaving when you don't get what you want, just because your parents failed to raise you

DAD I WANTED A LAMBO NOT A FERRARI, T_T WAAAA FUCK YOU

You wanna pull a Caillou now?? Grow up..
