'is gradually forgotten' is the definition.
(I've seen this in another clue)

'with the punch-up at an end' is the wordplay.
'with' says to put letters next to each other.
'the punch-up' becomes 'blows' (I can't explain this - if you can you should give a lot more credence to this answer).
'at an end' becomes 'over' (I've seen this in another clue).
'blows' next to 'over' is 'BLOWS OVER'.
