Trail a twisted noose (6)
I believe the answer is:
lariat
'noose' is the definition.
(I've seen this before)
'trail a twisted' is the wordplay.
'twisted' is an anagram indicator.
'trail'+'a'='traila'
'traila' anagrammed gives 'LARIAT'.
(Other definitions for lariat that I've seen before include "Line of cowboy" , "A cowboy's working rope" , "A cowboy's rope used to tether a horse" , "Gear for cattlemen" , "Cowboy's rope, lasso" .)
