Stupid person cutting end off sun-dried meat strips (4)
I believe the answer is:
jerk
'stupid person' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for jerk that I've seen before include "Sharp tug" , "Pull suddenly - twerp!" , "dull person" , "Jolt; tug" , "Yank; preserve (beef)" .)
