Cheat foolish twits (5)
I believe the answer is:
twist
'cheat' is the definition.
(I've seen this before)
'foolish twits' is the wordplay.
'foolish' indicates an anagram.
'twits' is an anagram of 'TWIST'.
(Other definitions for twist that I've seen before include "Rotate -- dance" , "Wrench, distort" , "Change - 1960s' dance" , "Tobacco - fraud - unexpected development - dance" , "Sprain, turn, wrench" .)
