The Word of the Day from The Zombie Cause Dictionary by Doc Lucky Meisenheimer is ZEIZURE.
ZEIZURE – Uncontrolled spasms and shakes as residual cortical brain functions rebel against the viral nanotubular network control. Zombies typically remain in an erect position. Zeizures are most common when a zombie tries to attack a former family member or friend. This occurs more frequently in later stage Beating Heart Zombies and early Aystole Zombies. It rarely occurs in late stage Black Zombies. Zombies may or may not go into a zorpor after a zeisure.
