Umm, I could be wrong, . . . but I've been told that in the U.K. "berk" is bad slang for a woman's genitalia. (Equivalent to c**t in the U.S.) If I'm wrong, someone please correct me.
This might not concern you if you don't live there. But once I heard that I couldn't get it out of my mind. Then again, Berkely isn't my style for a girl anyway so I haven't worked that hard at it.
For what it's worth.
