"Brock's home!" all-rounder spat (5)

I believe the answer is:

setto

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

'brock's' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'home all-rounder spat' is the wordplay.
I cannot really understand how this works, but
'home' could be 'sett' (type of animal home) and 'sett' is found within the answer.
'all-rounder' could be 'o' and 'o' is found within the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?

(Other definitions for setto that I've seen before include "Fight" , "argument" , "battle" , "Start" .)
