Son having a nap outside pub yard in birthday suit, soaking wet (6-7)
I believe the answer is:
skinny-dipping
'son having a nap outside pub' is the definition.
I can't judge whether this defines the answer.
'yard in birthday suit soaking wet' is the wordplay.
'yard' becomes 'yd' (abbreviation).
'in' means one lot of letters goes inside another.
'birthday suit' becomes 'skin' (I've seen this in another clue).
'soaking wet' becomes 'nipping' (I am not sure about this - if you are sure you should believe this answer much more).
'skin'+'nipping'='skinnipping'
'yd' placed within 'skinnipping' is 'SKINNY-DIPPING'.
Can you help me to learn more?
(Other definitions for skinny-dipping that I've seen before include "Swimming naked" , "Swimming in one's birthday suit" .)
