'repressed emotion' is the definition.
I know nothing about this answer so I can't judge whether this works.

'breaking its bone with impudence' is the wordplay.
'breaking' is an anagram indicator.
'with' says to put letters next to each other.
'impudence' becomes 'lip' (lip is a kind of impudence).
'its'+'bone'='itsbone'
'itsbone' with letters rearranged gives 'bitones'.
'bitones'+'lip'='BIT ONES LIP'

'and' is the link.
