My German is not super-dooper, but from what I gather it may be that the first line should read like this:
"Ja, die regen doch über cool"
and,
does "cool"stand for a name? If it does not, then the sentence should again be differently written, I think. But perhaps is the name of a band, or something.
Yes, you are absolutely right Andreea, "cool" stays "cool" in German. It's not really a word I would use in a German test, but it's quite popular especially among young people.
I changed a few words that were spelled incorrectly and I deleted "uber" (die reden uber doch cool) because it didn't make any sense to me (even not as "über" )
