So that's a shirt that specifically asks mathematicians and physicists to not be jerks? Because...? – Jonas Mar 17 '13 at 16:23

This question is not that bad, it is about the physical meaning of the time derivate of the acceleration and therefore a legitimate physics question. So it need not to be closed or something as certain people claim ... – Dilaton Mar 17 '13 at 20:50
    
An oxymoronic T shirt? :-) – John Rennie Mar 18 '13 at 8:25

At first, I thought, "Don't be a jolt", what does that mean? Then, I remembered that in some countries, it is called "jerk". – centralcharge Jun 22 '13 at 5:32

It means don't be a jerk. The third derivative of position (i.e. the change in acceleration) is called "jerk", though it's a little used quantity. It's called jerk because a changing acceleration is felt as a "jerk" in that direction.

In physics, sometimes the third derivative of position with respect to time is called jerk.

Jerk is the third derivative, fourth derivative is jump.
