Ashtray array (5)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
butts
'ashtray array' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for butts that I've seen before include "Objects of ridicule" , "Target range" , "Target area" , "Large beer casks" , "Victims" .)
