Playful young man (3,3)
I believe the answer is:
toy boy
'playful young man' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'playful young man' is the wordplay.
'playful' becomes 'toy' (I am not sure about this - if you are sure you should believe this answer much more).
'young man' becomes 'boy' (a boy is a male child).
'toy'+'boy'='TOY BOY'
Can you help me to learn more?
(Other definitions for toy boy that I've seen before include "Older woman's younger lover" , "Older woman's fancy" , "Young male lover of older woman" , "Woman's young lover" , "Much younger male lover of older woman" .)
