Tobacco shoot (4)
I believe the answer is:
plug
I believe this is a double definition.
'tobacco' is the first definition.
(I've seen this before)
'shoot' is the second definition.
(I've seen this before)
(Other definitions for plug that I've seen before include "Fitment at the end of a flex" , "Wad, of tobacco say" , "Blatant promotion" , "Stopper - advertisement" , "Shoot" .)
