Thanks JJ109 and DannyK13 - should have included the letters I had in my question - they are D?C? so not "bent", though that could have been the right answer...
Thank you all. I thought either "dick" or "dicy" but couldn't decide which, or indeed if correct.
aelmpvw: the 'c' comes from 8d "make rude gestures at bird, one's over recess" (my answer "cock a hoop" - "a hoop" fits with the relevant across answers)
Thanks Mamyalynne - you are of course correct and "cock a snook" is in fact what I had for that clue. No idea where "hoop" came from as not even enough letters!
So still left with the dick/dicy dilemma....
