a state, commonly seen in preteen girls, in which one becomes very excited, hyperactive and giggly. This can happen randomly but is commonly induced by having a crush who likes them back or other silly dramatic things like that.
Cassy just told me that Thomas likes her + now she's all twiderpated and won't shut up.
When someone is completely flustered over something very easily understood, or when they just cant seem to grasp the general concept of why some one is doing what they are doing.
Ie. She was all twiderpated when her friends told her that her hair looked awful.
Ie. "Dude shes like 250 in a bikini, im all twiderpated, how'd she get that thing on?"
