A perpetual state of abundant anticipation for an event to occur later in the evening, usually on a Friday or Saturday night and often, if not always, involving alcohol, alcoholism, drunken activities, in home stripper poles, a group of ten or more people, Jagermeister shots from silicone inserts, gratuitous or full frontal nudity, trashed apartments/homes, "don't pass out with your shoes on!" rules, and the occasional fist fight resulting in a life long BROmance or in coed circumstances marriage. The eventuality of this mental state could be the worst hangover or the best night of your life. Sadly, neither are remembered the majority of the time.
