When one either watches a movie trailer, reads a book, or sees a trailer for a new game and becomes overly excited about it, to a freak out state of mind, causing one to go into shakes, fits, and outbreaks of rage, shock, giddiness, disbelief, or just general excitement. Perferably, the subject of the movie, book, or game is something that people would classify as being dorky or nerdy.
*Watches the trailer for the final Harry Potter film* Oh my god!!! I NEED TO SEE THAT! I HAVE TO WAIT UNTIL FUCKING JULY?!?!?!?! NOOOOOOOOOOOOOOO!!!!!!!!!!!!! I CAN'T WAIT THAT LONG!!!! WHY CAN'T IT COME NOW?!?!?!?! *Fits and tantrums and dorkilepsy insues*
