Twisted look
I believe the answer is:
sneer
'twisted look' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for sneer that I've seen before include "Scoff, scorn" , "A scornful expression or remark" , "Smile contemptuously" , "Speak contemptuously" , "Contemptuous or mocking smile" .)
