Get bent out of shape (4)
I believe the answer is:
warp
'get bent out of shape' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for warp that I've seen before include "Go out of shape" , "Crane fly larva" , "Become bent like timber through heat" , "Become twisted" , "Misintepret" .)
