Tactless Argentine cowboy gets energy to chase the duck away (6)
I believe the answer is:
gauche
'tactless' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for gauche that I've seen before include "Lacking grace" , "Unsophisticated and socially awkward" , "Clumsily tactless" , "not right for Parisian" , "Graceless" .)
