A jerkait is an elongated lure made to imitate an injured baitfish such as a shiner or minnow amongst others. The jerkbait has no action of its own. The action is created by the angler. This is done by jerking your rod as you reel in the lure. Every time you jerk the rod, the bait will shoot off in different directions. This imitates the last swimming strides of a dying baitfish, which is a dinner bell for bass.
