Eres tan fresco
Spain is so cool because it is :)
This is idiomatic, so it may differ based on place. In Spain, they would say: "que superguay!"
Ya takoy krutoy! (I am so cool)
This is jargon in English, and the answer varies depending on location. One common way to say "That's cool" or "How Cool!" is Que Guay In Spain, another way to say that something is really cool, you can say "____ es la leche." You can, of course, change that depending on the subject (by conjugating ser differently)
je suis tellement cool
In Spain, the word for cool is "guay".
santa nicolas
say so are you (if you mean it) and smile when you say it.
Well Spain are out and Paraguay aren't in it, so I say yes :-)
Du bist so cool!
Translation: Eres, de verdad, tan bonito/a y guay.Note that the word "guay" is popular in Spain, but less popular in Latin America. Some other words that may be more popular are "genial", "chévere", "chido", and "cool".
Miranda is spelled cool but it don't make you famous to have this name so I say Miranda is not a cool name.
