jerk (v.1)

"to pull," 1540s, "to lash, strike as with a whip," of uncertain origin, perhaps echoic. Related: Jerked; jerking.

jerk (v.2)

as a method of preserving meat, 1707, American English, from American Spanish carquear, from charqui (see jerky). Related: Jerked.

jerk (n.2)

"tedious and ineffectual person," 1935 (the lyric in "Big Rock Candy Mountain" apparently is "Where they hung the Turk [not jerk] that invented work"), American English carnival slang, of uncertain origin. Perhaps from jerkwater town (1878), where a steam locomotive crew had to take on boiler water from a trough or a creek because there was no water tank [Barnhart, OED]. This led 1890s to an adjectival use of jerk as "inferior, insignificant." Alternatively, or influenced by, verbal phrase jerk off "masturbate" [Rawson].

jerk (n.1)

1550s, "stroke of a whip," from jerk (v.1). Sense of "sudden sharp pull or twist" first recorded 1570s. Meaning "involuntary spasmodic movement of limbs or features" first recorded 1805. As the name of a popular dance, it is attested from 1966. Sense in soda jerk attested from 1883, from the pulling motion required to work the taps.
