Cool way to join clubs with wine (6,4)
I believe the answer is:
street cred
'cool' is the definition.
(a cool reputation)
'way to join clubs with wine' is the wordplay.
'way' becomes 'street' (street is a kind of way).
'to join' is a charade indicator (letters next to each other).
'clubs' becomes 'c' (abbreviation used in card games such as bridge).
'with' says to put letters next to each other.
'wine' becomes 'red' (red is a type of wine).
'street'+'c'+'red'='STREET CRED'
(Other definitions for street cred that I've seen before include "Acceptability in popular culture" , "rapport with the people?" , "Social acceptance by young townies (slang)" , "status in the city - with 12a" , "Smartness" .)
