A person who lives in the Pine Barrens of Southern New Jersey and is given to wearing unbuttoned flannel shirts with Lynyrd Skynyrd or Molly Hatchet tour shirts underneath. Most frequently sited in Southern Ocean County and environs. Known for yelling, "Freebird!" whenever they are in the audience at a live concert in the hope that there are other Skynyrd fans there that they can hook up with to drink beer and fight with later. To date, no band has actually ever played Freebird at the request of a Piney.
