Joints . . . or some macaroni (6)
I believe the answer is:
elbows
This clue is a double definition.
'joints' is the first definition.
(I know this)
'some macaroni' is the second definition.
(I've seen this in another clue)
(Other definitions for elbows that I've seen before include "involved in the movement of arms" , "Arm-joints" , "Hinged arm joints" , "that make army manoeuvres possible" , "Bend them and have a few drinks" .)
