Simply put, a tweenebe is a parent or adult who is inspired to live the carefree life of a tween. Tweenebe's are popping up everywhere! They're the parents who want to see High School Musical on ice, the ones who actually want to see Hannah Montana live. These parents actually ENJOY the same things as their tweens, and love that they have access to so much yet have no responsibility. For reference, please see middle-aged dad jamming out to favorite rock band in the garage. Total tweenebe.
