head over heels

'completely rapt' is the definition.
I can't tell whether this defines the answer.

'chief finished with stilettos' is the wordplay.
'chief' becomes 'head' (synonyms).
'finished' becomes 'over' (over can mean finished or ended).
'with' means one lot of letters go next to another.
'stilettos' becomes 'heels'.
'head'+'over'+'heels'='HEAD OVER HEELS'

'say' acts as a link.

Can you help me to learn more?
