Topless man craves small pleasure (9)
I believe the answer is:
happiness
'pleasure' is the definition.
(thesaurus)
'topless man craves small' is the wordplay.
'topless man' becomes 'hap' (I can't justify this - if you can you should believe this answer much more).
'craves' becomes 'pines'.
'small' becomes 's' (abbreviation - e.g. clothes size).
'hap'+'pines'+'s'='HAPPINESS'
(Other definitions for happiness that I've seen before include "Great contentment" , "Joy, well-being," , "Felicity" , "State of well-being, contentment" , "Cheer" .)
