According to the Wikipedia page:
Hurricane Bawbag is the colloquial name given to an intense mid-latitude storm that brought hurricane-force winds to Scotland during the week beginning on 5 December 2011. The storm also brought prolonged gales and rough seas to many other regions within the British Isles. On 8 December, winds reached up to 165 mph (265 km/h) at elevated areas, with sustained wind speeds of up to 80 mph (135 km/h) reported across populous areas. The winds uprooted trees and resulted in the closure of many roads, bridges, schools and businesses. Overall the storm was the worst to affect Scotland in 10 years.
Looking at how this compares to the Saffir-Simpson Hurricane Scale, the sustained wind speeds in the populous areas would put it at a Category I storm. However in the upland areas, a 165 mph wind speed would put in well within the requirements for Category V!
The Scots - always ready to name their own hurricanes, thank you very much, they don't need a German name for what hit them and not Germany - renamed Friedhelm, giving it the moniker "Bawbag", which is the Scots equivalent of "ball-bag" (i.e., "scrotum"). I suppose if you were to do a reverse translation back into German (and gave it the cultural implication likely behind the renaming of "Bawbag"), you'd likely get "sackgesicht".
And, the Sensational Alex Salmond Gastric Band produced this music video (showing the impacts of Bawbag hitting Scotland):
Now, all of this raises the questions of why is a hurricane hitting Scotland? What is a hurricane doing outside of hurricane season? How come such a storm is so friggin' strong?
