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].
