Forking is actually a real (albeit slang) term for sticking plastic forks in someone's yard. A prank - similar to toilet papering their house / yard. WWAY didn't make the word up, and it's not a joke about "the f-word" as someone else mentioned, but I feel it's relevant to the case because he has some history of legal woes with other students. Perhaps this "sexting" thing is just another prank that has gotten out of hand and now no one is stepping forward to set the record straight.
