'greet affectionately' is the definition.
I can't tell whether this definition defines the answer.

'triumph at weekend' is the wordplay.
'triumph' becomes 'win' (a win is a victory or triumph).
'at' is a charade indicator (letters next to each other).
'weekend' becomes 'k' (I've seen this in other clues).
'win'+'k'='WINK'

'after' is the link.

Can you help me to learn more?

(Other definitions for wink that I've seen before include "Convey an amused understanding" , "Sleep moment; twinkle" , "Conspiratorial eye movement" , "in a trice" , "Close eye briefly" .)

I've seen this clue in The Irish Times.
