'the other not repeated' is the definition.
I can't tell whether this defines the answer.

'two from three bedside tables' is the wordplay.
'two from three bedside' becomes 'onenight' (I can't justify this - if you can you should give a lot more credence to this answer).
'tables' becomes 'stands' (stand is a kind of table).
'onenight'+'stands'='ONE-NIGHT STANDS'
