Jerk end of pancake in (5)
I believe the answer is:
creep
'jerk' is the definition.
(I've seen this in another clue)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for creep that I've seen before include "Inch" , "Sycophant" , "snake" , "Tiptoe" , "Slow motion" .)
