A term used in the popular video games Call of Duty: World at War and Call of Duty
: Black Ops
when playing the Zombie
It refers to a zombie which has had its legs blown off by a grenade. These zombies are typically extremely slow, but can be dangerous if a player is not vigilant.
Because a round does not start until all zombies are killed, they are often kept alive at the end of rounds to purchase ammo, perks, and guns without starting the next round.
Damn it, a crawler got me because I wasn't watching the ground.
