Cheat silly twits (5)
I believe the answer is:
twist
'cheat' is the definition.
(I've seen this before)
'silly twits' is the wordplay.
'silly' is an anagram indicator.
'twits' anagrammed gives 'TWIST'.
(Other definitions for twist that I've seen before include "Misrepresent - dance" , "Wind spirally" , "Unexpected event" , "title character" , "See 1" .)
