a. A serpent-like monster rumored to be living in Loch Ness.
b. Rumored to be the child of Bella and Edward Cullen. Her real name is Reneesme, which comes from combining the names of Bella and Edwards moms, Renee and Esme. It takes Nessie only 6 years to be fully grown, and since she's extra speshul, she even glows like radioactive waste. It is also rumored that werewolf Jacob imprints on her. Her existence is accepted among many, but is still unproven.
a. Oh my God, I just saw Nessie poke her head out of the loch!
b. A few days before the release of Breaking Dawn, rumors of Bella and Edward's child Nessie leaked onto the internet, causing weeping and gnashing of teeth as people denied it. The main argument for this being fake was that it was impossible for vampires to have children. Others claimed it was ridiculous. Either way, it brought many lulz.
