Europeans talk nonsense around southern prisoner (7)

I believe the answer is:

gascons

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

'europeans' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.

'talk nonsense around southern prisoner' is the wordplay.
'talk nonsense' becomes 'gas' (I've seen this in another clue).
'around' is an insertion indicator.
'southern' becomes 's' (abbreviation).
'prisoner' becomes 'con' (abbreviation for 'convict').
's'+'con'='scon'
'gas' enclosing 'scon' is 'GASCONS'.

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
