An adult who never grew up. Not necessarily a bad person, but someone who doesn't have motivation to achieve independence outside of his parent's domain.
Usually a kidult is characterized by living in their parent's basement (typically male), have an inability to find a job and usually addicted to video games.

Someone that, in adulthood, proudly maintains juvenile tendencies. A kidult may be 39, yet still play video games and drink energy drinks, and kick ass at both.
Hells yeah I got the new CoD on my xbox 720*, fool. I'm a kidult after all.
