I thought I would get a quick reply with information about this since a lot of people seem to have seen this place at least once, because there are sometimes chit-chats with many messages. Sometimes there are users in there!

So... 'bin ich Big' sounds like German to me and according to Google translator it means "I'm big"... so there are people editing that place as a joke I guess, but what I don't understand is why the app redirects me to that place.
I tried to zoom out to see where on earth this place is, and I could see the city name of "Fiumefreddo" at the north and some cyrilic-like names to the east of that, before the app crashed. I think the place is located somewhere in the Mediterrian Sea.
