Debacle :)
"Debacle" is a word with a silent "b" that means a sudden and ignominious failure or a fiasco.
Fiasco or debacle could be good options for describing a failed attempt in a more sophisticated manner.
The nature of the debacle is never explicitly stated.
Once the little girl knocked over the tree there became a debacle.
I found that I had gotten myself into a hopeless debacle with my girlfriend forgetting her birthday.
