What it is

In a quarterback sneak the quarterback takes the snap and dives forward right behind the center, trying to gain a very short distance.

In a game

It is used when only a yard or less is needed, such as on fourth and one or near the goal line. The offensive line pushes forward, and the quarterback follows it low and fast.

More detail

It is one of the highest-percentage short-yardage plays, because the quarterback is already in position and there is no exchange. Teams with strong centers and low-pad-level linemen use it often.
