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

'this will wound a greedy' is the definition.
The definition suggests a singular noun which matches the answer.

'person's heart' is the wordplay.
'person's' becomes 'pigs' (pig is a kind of person).
'heart' becomes 'ticker' (informal term for the heart).
'pigs'+'ticker'='PIGSTICKER'
