Question

Is saying “Oh, you won’t believe the fiasco that just went down”

A proper use of the word fiasco ?

Answer 1

Yes and no. A more appropriate sentence for the word "fiasco" would be: "Her plans turned into a fiasco." Remember, synonyms for the word "fisaco" are disaster, catastrophe, and failure, which help to use the word in a sentence. You would imagine the sentence first as "Her plants turned into a disaster" and then apply the word fiasco.

Good luck, hope this helped!
