i once had an old korean lady look at me absolutely terrified during a street PK touch routine then ran away shouting, my half korean friend was laughing his ass off and when i asked him what she said, he said that she was calling me the devil
but on the occaisons where thyd rather know how to do it than run away in fear i usually reply, "with impeccable skill" or "by not having a social life" or "did what?"
