I Googled up the word "debacular" and got 72 hits. I'm glad in a way that the word already exists but bothered by the fact that I wasn't able to claim credit for creating such a useful word. Still, I will make it a point to use the word constantly so that it enters mainstream usage and subsequent online searches will pull up hundreds upon hundreds of hits.
And if it wasn't clear from the word itself, just as a spectacle is spectacular, a debacle is debacular. Adjectival forms. Learn them. Love them.
