Outing for dance (4)
I believe the answer is:
trip
I believe this is a double definition.
'outing' is the first definition.
(I've seen this before)
'dance' is the second definition.
(I've seen this before)
'for' acts as a link.
(Other definitions for trip that I've seen before include "Set off for" , "Hallucinogenic drug experience - lose one's balance" , "blunder" , "Journey - miss one's footing" , "Hallucinatory experience" .)
