Aden Debord, 21. delves deep into the internet, playing games on-line, watching YouTube channels, etc. He says people as involved as he is sometimes risk encountering "trolls" --anonymous misfites whose sole purpose seems to be to attack others in remarkably cruel ways. His friend, Jim Newman, 73, is fascinated by the stories Aden tells. Partly because of the chilling nature of the attacks. But also because of the new words emerging in US English to describe such events!
