3 with sexy approach (4,4)
I believe the answer is:
chip shot
'approach' is the definition.
(type of approach shot in golf)
'3 with sexy' is the wordplay.
'i with' becomes 'chips' (I can't justify this - if you can you should believe this answer much more).
'sexy' becomes 'hot' (similar in meaning).
'chips'+'hot'='CHIP-SHOT'
Can you help me to learn more?
(Other definitions for chip shot that I've seen before include "what one may make with wood" , "a hit, of course" , "found in loft?" , "Short-distance attempt to reach the green" , "It may be used to escape hazard" .)
