Messed up badly (7)
I believe the answer is:
mangled
'messed up badly' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for mangled that I've seen before include "did butcher" , "Distorted" , "Damn leg may be mutilated" , "Chewed up" , "Mutilated - pressed clothes through a machine" .)
