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

'like a barrister or a judge?' is the definition.
I can't judge whether this definition defines the answer.

'get ticked' is the wordplay.
'get' becomes 'be' ('get' can mean 'come to be').
'ticked' becomes 'wigged' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'be'+'wigged'='BEWIGGED'

'off' is the link.
