A friend of mine who is from Barcelona often uses a word, which sounds like "shtrass" (I suppose it might be spelled estrás, but it don't find anything related on Google except a type of a stone). He uses it to express things like "incredible", "wow", "Oh my God", so a sort of an exclamation. Which word might it be?
I suspect the word you are looking for is
Which translates as oysters.
As indicated by the official language:
Eufem. por hostias.
- interj. coloq. U. para expresar disgusto, asombro, etc.
Del lat. hostia 'víctima de un sacrificio'.
hostia, u hostias
1. interjs. malsons. Denotan sorpresa, asombro, admiración, etc.
That is, ostras is an interjection to show annoyance, surprise and many other things. The funny thing is that it is used instead of hostias (communion bread), which is an interjection marked by the dictionary as rude ('malsonante').
