Source

This item is a PvP reward, and can be purchased for 2,679 from:

• Grunnda Wolfheart <Frostwolf Supply Officer> in Alterac Valley
• Jekyll Flandring <Frostwolf Supply Officer> in Hillsbrad Foothills

This item was worn by Stan in the South Park episode "Make Love, Not Warcraft." This should not have happened seeing as this is only available to Horde whilst Stan plays a human.
