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

'out? i am surprised at you' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'put a mock warning' is the wordplay.
'put' is an insertion indicator.
'a mock' becomes 'sham' (both can mean fake).
'warning' becomes 'fore' (shouted in golf).
'sham' put into 'fore' is 'FOR SHAME'.

Can you help me to learn more?
