Shock problem arising from acrobatic manoeuvre over object (5,4)
I believe the answer is:
split ends
'shock problem' is the definition.
('shock' can mean hair)
'acrobatic manoeuvre over object' is the wordplay.
'acrobatic manoeuvre' becomes 'splits' (as in doing the splits).
'over' means one lot of letters goes inside another.
'object' becomes 'end' (both can mean a goal or purpose).
'splits' placed around 'end' is 'SPLIT ENDS'.
'arising from' acts as a link.
(Other definitions for split ends that I've seen before include "damaged locks" , "hairy problem" , "Slip tends to create unsightly hair condition" , "Hair problem" , "Dry hair" .)
