is "pu" the same as "ugh"

Question

I was randomely looking through my new (well it's 10 years old but it's new to me) spanish/english dictionary yesterday, and I happened apon the word "ugh" (who knew it was a word.) and the translation is "pu" To me this sounds hilarious, so I'm just checking if it's correct. ¡Gracis!

Answer 1

jajaja, I think onomatopeias cannot be translated, or they shouldn´t be translated.

For instance, roosters sound cock-a-doodle-do in English. But they sound something like kikiriki In Spanish
