Fiasco is a word from my childhood. I enjoyed the word, because it had a very strong meaning – a complete (usually humiliating) failure – but it was not a swear word. I used it very often at a young age.
Historically, fiasco comes from both French, fiare fiasco, «turn out a failure» (19c.), and from Italian far fiasco «suffer a complete breakdown in performance,» It first appeared in around 1855 meaning a bad theater performance. Soon it took on a broader meaning of any failure or bad flop. Etymonline.com
Hopefully you won’t have any fiascos in your near future!
