Would someone be a dear and explain the joke here?

Not a native, but a translator at least...

It looks like the joke lies in the fact that "caballeros" can mean either "men", or there's a term... "fue armado caballeros", meaning "he was knighted" literally. (In which case "caballeros" is a very...archaic, I guess, term for "knight".)

I'd guess someone was poking a little bit of fun translating there. (Or it COULD just be epic translation fail, but I'm inclined to think it was deliberate simply from the word "restroom". The connotations of that word are literally a room where you can rest - someone unfamiliar with the peculiarities of English would be rather confused. "Bathroom" would be more understandable, I think. Then again, I am a bit of a pedant...)

I don't know the languange itself but for me it's a plain "bathroom for men"

Thanks for taking the time to explain that one, TachyonStar. Those wily Spanish speakers!

Kireek, I'm fairly certain there is some kind of play on words behind this given the site it's come from.

9gag?

"caballeros" in portuguese means "cavalheiros" or "senhores", as in a term to define men or gentlemen, but it also means "cavaleiros" wich is knights in english.
Yes cavaleiros and cavalheiros mean the same thing in spanish, we know what it means because of context, if we wanted translation we would see the context 1st and not make the caballeros -> knights

No problem, Spog. I kind of have trouble not helping out with translation. The woes of self-studying languages for over ten years.

I'm a native spanish speaker, despite it's been made clear already, i'll give my opinion about it anyway (see if it can clear any doubts left )

Well it's pretty much as you guys said, Caballero means usually Gentleman. But it also means Knight as in the middle ages. It's not archaic, it's just that you don't come in the need to use the word "knight" very often.

That's the joke, at first I tought it was an epic translation fail, now Tachyon gave me more to think that way:

I hadn't tought about the restroom/bathroom thing, my guess is that since the word Gentleman is used and not the word Man in spanish, the person translating it was inclined to look for "elegant" words before common ones. So this person got it right with the restroom instead of bathroom, but got it wrong with the Knight.

Ah, many thanks. I'd actually made the topic with you answering it in mind! Pleased at the broad response it got.

So all in all, it's a bit of a shitty joke?

I personally liked it a lot when I saw it on 9GAG, it made me laugh

I'm not sure if this was intentional, but I snickered a little bit since this is in regards to a restroom joke.
