Shoot the dope! (3)
I believe this is a double definition.
'shoot' is the first definition.
(I've seen this in other clues)
'the dope' is the second definition.
(both can informally mean cannabis)
(Other definitions for pot that I've seen before include "Weed" , "...Karenina(Tolstoy)" , "Cooking utensil or illegal drug" , "prize" , "Trophy; kitty" .)
This might be a double definition.
'shoot' is the first definition.
(thesaurus)
'the dope' is the second definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps there's an association between them I don't understand?
Can you help me to learn more?
(Other definitions for sucker that I've seen before include "One easily fooled; base-of-stem shoot" , "Slangily, one who is easily deceived" , "Gullible person (colloq.)" , "Naive type: shoot" , "Mug - one using a straw?" .)
