Here’s a word for you: Gigundous.
As in, “Look at that house on the hill. It’s gigundous!”
This is how I think it would be spelled, but to tell you the truth I’ve never seen it spelled. I don’t believe it’s a formal, Webster’s-approved word. But I hear it all the time.
Do you use this word? Where the heck does it come from? How would you spell it? And how would you define it? What would qualify as gigundous, and what wouldn’t make the cut?
