Hell, yeah, it’s a word. If people use it with a consistent meaning, it’s a word whether it’s in the dictionary or not. Since I’ve never heard anyone use “humongous” without meaning “huge”, I’d classify it as an American English slang term, not limited to a specific in-group. Now here’s the fun…who feels like looking up the origins of “humongous”? My bet is that it’s 60s or 70s California surfer slang that then hit the rest of the country during the “Valley Girl” craze of the early 80s.
