It seems like its a brutal nickname. The "Gore" zone seems to refer to the area after the emergency-cushion is damaged.
Normally, that area has a barrier designed to save lives, by slowing down cars and providing cushioning. However, the emergency-cushion was already damaged from a prior crash.
Without an emergency-cushion, running into a straight concrete barrier has known, lethal consequences.
