An annual survey conducted by Business Insider magazine has concluded that Ashburn, Va. is the nation's most obscene city -- stealing the crown from last year's winner, Herndon. The survey used comedian George Carlin's famous "seven dirty words you can never say on television," plugged them into Google Trends, and then assigned a score to cities across the country based on the frequency of foul terminology in their Web searches. This year, Ashburn took the prize. (Herndon stayed on the list, taking third place, according to the survey.)
