Used when someone is completely pwned. This may only be used in a group of people and after zwah, zing, and zwoosh have been called. This also must be said while using a hand motion to signify the total pwnage. This hand motion includes turning your hand palm up, then moving it up and away from you as you elongate saying "zipppapotamus." All spellings include tree continuous p's.
Mike: Man, i just can't figure this out.
