Go to join street meeting (5)
I believe the answer is:
tryst
'meeting' is the definition.
(tryst is a kind of meeting)
'go to join street' is the wordplay.
'go' becomes 'try' (both can mean an attempt).
'to join' says to put letters next to each other.
'street' becomes 'st' (abbreviation).
'try'+'st'='TRYST'
(Other definitions for tryst that I've seen before include "Romantic rendezvous (literary)" , "Romantic assignation" , "meeting with another person" , "Lovers' appointment" , "where lovers meet" .)
