I see strange spelling and words in movie subtitles and books quite often. There are spellings like "ick" instead of "ich" and phrases like "Wat ist n det für n Blödsinn?". I need some online dictionary or a reference to be able to translate such things. Can you recommend some?
What you mean is the Berliner slang. I think there's no translator like Google Translator or Leo.org available, because even people who use this language often don't really know how to write the words correctly :D
But you may find the most important phrases and words here: http://www.spreetaufe.de/berlinerisch-berliner-jargon/woerterbuch-berlinisch-a-h/
