Rhona regularly squeezes misshapen orange sponge (6-2)
I believe the answer is:
hanger-on
'sponge' is the definition.
(thesaurus)
'rhona regularly squeezes misshapen orange' is the wordplay.
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
'squeezes' indicates putting letters inside (squeeze can mean hug or embrace).
'misshapen' indicates an anagram.
The alternate letters of 'rhona' are 'hn'.
'orange' anagrammed gives 'angero'.
'hn' enclosing 'angero' is 'HANGER-ON'.
(Other definitions for hanger-on that I've seen before include "Someone who tags along" , "Sycophantic associate" , "Social leech" , "Persistent follower" , "An unwanted follower or dependant - swings out of you" .)
