We had a German consultant in a few weeks ago, a fellow out of Cologne Germany. He was talking to a friend about beer and crazy translations, and mentioned that his father and brother like a beer called Pubarschknall. According to him it literally translates as "fart a$$ bang" and was named because when the beer would get somewhat old it would cause some serious digestive disruption. I looked it up on the web and apparently its a brown ale that is only 1% ABV. One web translation had it as "beer-fueled flatulence", just slightly less surly than the literal meaning mentioned earlier.
Just thought I'd share, and see if anyone has tried this ale.
