Distorting (8)
I believe the answer is:
twisting
'distorting' is the definition.
('twist' can be a synonym of 'distort')
This is the entire clue.
(Other definitions for twisting that I've seen before include "Distorting; coiling" , "Winding (together); distorting" , "Distorting, turning" , "Crooked" , "Cheating; distorting" .)
