Crapzilla is an exclamation (also called an interjection) that expresses strong emotion; when plans, intentions, things, life go epically wrong. This exclamation stands on it's own, and in writing it is followed by an exclamation mark. Crapzilla is to be used when a simple "crap" does not sufficiently capture the over the top, grand, larger than expected, as large as Godzilla fail that you are faced with.
