'a lot of cheek' is the definition.
I can't tell whether this defines the answer.

'johnny heartlessly pinches hooter' is the wordplay.
'heartlessly' says to hollow out the word (remove centre letters).
'pinches' is an insertion indicator (pinch can mean to steal).
'hooter' becomes 'owl' (owls hoot).
'johnny' with its centre taken out is 'jy'.
'jy' enclosing 'owl' is 'JOWLY'.

'showing' acts as a link.
