Bad gent and I get into trouble arguing? (8)

'arguing?' is the definition.
('debate' can be a synonym of 'argue')

'bad gent and i get into trouble' is the wordplay.
I cannot quite see how this works, but
'gent' could be 'bat' and 'bat' is found in the answer.
'and' could be 'n' (common abbreviation for 'and') and 'n' is found in the answer.
'i' is present in the answer.
The remaining letters 'deg' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
