Similar to a forest fire, a zombie fire is when a large horde of zombies catch fire. A zombie fire happens when a zombie horde is so close-knit that when one zombie catches on fire, the fire rapidly spreads to all the other zombies in the horde; just like kindling. The use of molotov cocktails on zombie hordes is a known cause of the zombie fire phenomenon.
