Wobble; bobbin (4)
I believe the answer is:
reel
I believe this is a double definition.
'wobble' is the first definition.
(I've seen this in another clue)
'bobbin' is the second definition.
(I know that bobbin can be written as reel)
(Other definitions for reel that I've seen before include "Highland dance" , "Folk dance" , "Lively dance and angler's spool" , "Film spool" , "Lively Scottish dance" .)
