'football's first half' is the definition.
I can't judge whether this defines the answer.

'met friends having liaised to come out' is the wordplay.
'met friends' becomes 'soc' (I can't justify this - if you can you should give a lot more credence to this answer).
'having' is a charade indicator (letters next to each other).
'to come out' indicates anagramming the letters.
'liaised' anagrammed gives 'ialised'.
'soc'+'ialised'='SOCIALISED'

'after' is the link.
