I agree with the other comments, but I also must say I agree with dmmaus as well. I try not to use the hint button for words I´ve already seen, but in this case proprio as in own would not make any sense...they should have just thrown the 2 new words at us, not 3 as it turns out.
I don't get this. Being a non-native English speaker (Swedish, really) I'm not even sure what the English translation means? Is this something you would say to someon who has made an outlandish remark, or is it just commenting that someone stepped out on the patio, or is it an insult or what?
You can say you're out of place to mean you've physically moved...though most often we would say, you've STEPPED out of place. The most common use for that is, as you stated, when someone has made an inappropriate remark.....now all that said, it doesn't much help either of us with the Italian.
I researched this with Google. It is a common phrase (102,000 hits). Here are some examples of usage
@mengonimarco è vero che sei omosessuale? (is it true you are gay)
@francerus ....é vero che sei proprio fuori luogo? (is it true .... )
From a forum:
se pensi di far ridere inanellando una sequela di parolacce, sei proprio fuori luogo
(if you think you make people laugh by stringing together a string of ❤❤❤❤❤❤❤❤(?), ...)
From another forum:
ma se questo tuo topik è per deridere il "Nostro" sesso, allora sei proprio fuori luogo
(but if this topic of yours is to mock "our" sexuality, then .... )
And finally a comment that I leave as an exercise for the reader:
sei proprio fuori luogo....cmq, vuoi che ridiamo??? ahahah
So what does it mean? Nothing. It is a phrase that has a usage but no meaning. The usage
is that when someone says something you think is completely inappropriate you tell then
sei proprio fuori luogo ... and perhaps they hit you?
Where I live (Canada), we would say "You are really out of line" to someone who had said something inappropriate. The English sentence in this duolingo example would have more the sense of not fitting in, being out of your element. If I were to find myself at a monster truck rally, for example. :) However, reading what Peter 2108 has found out about it, it seems like the Italian means the former. Also, if I may, your English is excellent, Olefattguy! I would never have guessed that it was not your first language if you hadn't said so.
American English here, though I'm pretty sure this works across all dialects. What immediately comes to mind when I hear this sentence is someone that looks like he does not belongs where he is, to the point that you bring attention to yourself. Like a man in a tuxedo at an amusement park, or a girl in pajamas at a wedding. (Though that's probably popular with the kids nowadays, who knows.)
