When a child is a show off and is as annoying as Bindi Irwin (daughter of the Crocodile Hunter, Steve Irwin). For those of you who don't understand the level of annoying that is Bindi Irwin it's sort of like when a kid acts like an over enthusiastic adult and act like they know the answer for everything. The child could possiblly have an over exaggerated and obnoxious laugh that makes you want to smack them in the face.
Child: I KNOW ALL ABOUT ANIMALS. I'm a grown up, I know everything blah blah blah blah blah blah! AHAHAHAHAHAHAHA!
Person: That kid has Bindi Irwin syndrome
