- A nickname for someone named Vanessa
People named Nessie are wonderfully complete people, more than skin deep. Beauty drips off of them and when the drops evaporate, they become the silver linings of clouds. A Nessie has wondrous beautiful eyes sparkling with clever untold plots. The name 'Nessie' is notable for the near impossibility of speaking it without smiling.
