'debauchery and stood over' is the definition.
I can't tell whether this definition defines the answer.

'saint worsened' is the wordplay.
'saint' becomes 'st' (abbreviation).
'worsened' becomes 'raddled' (I can't explain this - if you can you should give a lot more credence to this answer).
'st'+'raddled'='STRADDLED'

'by' acts as a link.
