Hello!

I'll be going to visit Ireland in March and I'm studying more to get around in the gaeltacht area (where my family is from). How do you say "brownie" in Irish? I can't find that in my dictionary. I'm also wondering how you would say more colloquial things like:

"That's cool, [it] sucks, " or any more slang like that, so I can understand my young relatives! Thanks!
