gaucho

I'm a little stuck... Click here to teach me more about this clue!

'cowboy' is the definition.
(term for a South American cowboy)

'awkward mostly over nothing' is the wordplay.
'awkward' becomes 'gauche' (I've seen this in another clue).
'mostly' means to remove the last letter (most but not all of the word).
'over nothing' becomes 'o' (O resembles 0. I am not sure about the 'over' bit.).
'gauche' with its final letter removed is 'gauch'.
'gauch'+'o'='GAUCHO'

'being' acts as a link.

Can you help me to learn more?
