look up any word, like donkey punch:
Completely unreal portrayal of kids on network television shows. A combination of Youth and Optimistic, it is the industry's attempt to reinforce "good" behavior, but instead induces teen eye rolling, sighing, and head shakes as they surf for something better.
Emily used to love to watch Brady Bunch reruns until she realized how youthimistic they were.
