KK is the common abreviation of Kaffe und Kippe which for those who does not speak German it is like Cofee and (hmm I dont know how to translate this in English :-( ) in Spanish it would maybe be "Cafe y Bachicha"?
This is what I found out that many people take as breakfast. Zigarrete and Cofee, I like Coffe.. Sometimes I smoke a zigarrete or two a month.. but this is not precisely my favourite Breakfast. However who can tell me this is not a common Breakfast. :-P
