@datarama haha! Yes, IMHO the peak swear word in Spain is "joder" and for emphasis some people roll the R (although that's not the correct pronounciation).

However, I have to be that guy that says that then it's a homophone with "gira" (it turns/spins, or "tour" [as in a musician's tour), so that dampens the effect :(

But I think it's fun to say "Jira está hecho en Java, ¡joder!"
