Starkid is a group of young actors that graduated from Ann Arbor acting school in Michigan. They quickly became famous on YouTube with their production of "A Very Potter Musical", a fan-made musical based off of the book by J.K.Rowling. They later went on to produce A Very Potter Sequel, Little White Lie, Me and My Dick and, most recently, Starship.
Starkid is also a name given to a member of the Starkid fan base, and a more dedicated fan base you will be hard pressed to find. "Starkids" are very protective of their own, and if going up against one of them you should be prepared to take on all the Starkids that leap to their defense. This is particularly true if you insult one of the Starkid cast.
Starkid is particularly famous for the easy going, laid back nature of their productions. The style of the performances usually allows for a lot of audience interaction. The friendly style of their shows are also added to by the inclusion of many inside jokes and pop culture references - both recent and classic.
The Starkid fan base grows more and more tight-knit as members of Starkid are becoming more famous and they are not very tolerant of those who claim to be fans of individual Starkids, yet have not bothered to incorporate themselves with Starkid Productions.
The Starkid members themselves are close friends. It is a common belief amongst the Starkid fan base that no matter how famous any individual member of the group becomes, Starkid will always be their "true home".
Joe Walker is my favorite Starkid!
I've seen all of the shows - I am a true Starkid!
They're not real Starkids, they haven't even heard of AVPM.
