Sayings in your native language that makes seem weird in english.

"Puedes llevar al caballo al rio y meterle su cabeza al agua, pero si no tiene sed, no tomara."

I'm forgetting the accents here, mind; this one translates to "You can take the horse to the river and dunk his head in the water--if he's not (feel free to add an 'ain't' there--this is a rural phrase) thirsty, he won't drink." Basically, you can try as hard as you can, but you can't force anything upon anyone.

I like ours: "You can lead a horse to water, but you can't make him drink." Same thing, really.

"...por un tubo y siete llaves".

This one sees a lot of use; it translates to "through a tube and seven faucets". It can be use in a phrase such as, "It's raining through a tube and seven faucets', which would mean it's raining a lot, or something similar.

Similar to "It's raining cats and dogs."

I've actually heard "The witches are getting married" for when it's raining hard...

That's kinda why portuguese is such as hard language to learn. I don't mean to put english down - I love englis and speak it when I'm talking to myself - put english is more of a practical language, and portuguese is a more rich language. Not just in number of words, but poetic possibilies, different forms of using it and so on... We have a LOT (big fat lot) of verbal tenses...I'm glad I've been given the skills in portuguese, people suffer in school...

My grandma used to say the angels are flushing there toilets for when its raining, and that they are bowling when it thunders.

[Archem]

I've heard the bowling one before, but the toilets one sounds reasonable.

[fruckert]

I like the toilets one
I've also heard that God is pissing on us for when it's raining
And then after that they remark at what he must be doing when it's snowing

HURRICANES ARE THE FLATULENCE OF THE LORD

The All Caps made that funny

When Mother Nature starts to PMS, bad things happen.  I use that one a lot.

[Desimodontidae]

HURRICANES ARE THE FLATULENCE OF THE LORD

Bad boy!

This whole rain stuff reminded me of one other phrase: "Está chovendo canivetes" - "It's raining pocketknives", but it's not used for rain, but to tell that something impossible happened/will happen, like:
person1: Hey dude, I'll study for the tests this time!
person2: Really? Then tomorrow will rain pocketknives!


Grandy said the best ones, though.

[Archem]

Sounds similar to "when pigs fly".

[fruckert]

I like that one
That's actually kind of cool

IT'S GOING TO RAIN POCKETKNIVES
AND IT SHALL BE PAINFUL

[Talt]

Thats different. You say the pig thing like in being negative. "You are only going to study when pigs fly." Pocketknives thing is like positive "You studying? zomg pocketknives shall rain"
Or something.

Pretty much this.
And "Pocketknives shall rain" got cooler, kinda apocalyptic...

I like that one
That's actually kind of cool

IT'S GOING TO RAIN POCKETKNIVES
AND IT SHALL BE PAINFUL

Caps made me laugh.
But indeed, I wondered about this expression a lot when I was a little kid... It was scary. My most useless thought at the time was "they come with the knives out or close and safe?"
Yeah, useless kid.
