Confound a wild party (5)
I believe the answer is:
abash
'confound' is the definition.
(I've seen this in another clue)
'a wild party' is the wordplay.
'wild party' becomes 'bash' (I've seen this in another clue).
'a'+'bash'='ABASH'
(Other definitions for abash that I've seen before include "Rattle" , "disgrace" , "Cause embarrassment" , "Crush" , "Humiliate" .)
