moobs

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

'man's chest' is the definition.
I know nothing about this answer so I can't judge whether this works.

'report back over small' is the wordplay.
'report' becomes 'boom' (both can mean a loud noise).
'back' shows that the letters should be reversed in order.
'over small' becomes 's' (abbreviation - e.g. clothes size. I am not sure about the 'over' bit.).
'boom' reversed gives 'moob'.
'moob'+'s'='MOOBS'
