'fifty from you and goes straight home before midnight using these' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'trendy ursula takes' is the wordplay.
'trendy ursula' becomes 'day' (I am not sure about this - if you are sure you should believe this answer much more).
'takes' becomes 'returns' (returning is a kind of taking).
'day'+'returns'='DAY-RETURNS'
