Possibly Cuban cad? (4)
I believe the answer is:
heel
This might be a double definition.
'possibly cuban' is the first definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'cad?' is the second definition.
('heel' can be a synonym of 'cad')
Can you help me to learn more?
(Other definitions for heel that I've seen before include "Shoe part - come here, Fido!" , "Despicable type" , "scumbag" , "that may be Cuban" , "despicable person" .)
