A term first said by Kaethan on the Frostmane(US) realm.
Instead of describing a Alterac Valley battleground as a "Turtle" in which the Horde camp Frostwolf Keep's ramp in the tower to the Frostwolf Relief Hut. He described it as a "Zebra" because of the Alliance running into death at the ramp fastly killing off all their reinforcements and the chance to win. This caused a epidemic of saying "zebra" as it was a new term to describe a "Turtle" AV.
