'silly talk' is the definition.
(I've seen this before)

'loveless pair become confused' is the wordplay.
'loveless pair' becomes 'tw' (I can't explain this - if you can you should give a lot more credence to this answer).
'become confused' becomes 'addle' (I've seen this before).
'tw'+'addle'='TWADDLE'

'in' acts as a link.

Can you help me to learn more?
