The state or quality of being jerky (characterized by sudden uneven motion or progress).
1962, Hansard, Incomes Policy, 4 July, 1962,
One reason why we get into difficulties in the public sector is the jerkiness with which this problem is dealt with. Teachers, or nurses, or bus drivers, or whoever it may be, are given a substantial rise. But then, for the next six or seven years no further increases are awarded to them and the Government suddenly wake up to the fact that these groups have fallen far behind everybody else.

[…] the rhythmic pattern […] contains the typical features of a gigue. The tempo should be chosen accordingly; it should be fast enough to depict the jerkiness of the gregarious dance, but not so rushed as to render the intricate patterns of imitations as a simple technical show.
(informal) The behavior of a jerk (unpleasant person).
