'girl working' is the definition.
The answer and definition can be both to do with contact as well as being present participle verbs.
Perhaps they are linked in a way I don't understand?

'outlaw foremost activity in rodeo' is the wordplay.
I cannot really see how this works, but
'activity' could be 'ass' (ass is a kind of activity) and 'ass' is found in the answer.
'in' is within the answer.
The remaining letters 'log' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...

'to' acts as a link.
