Plump for ripping new option: MBE! (10)
I believe the answer is:
embonpoint
'plump' is the definition.
('embonpoint' can be a synonym of 'plump')
'ripping new option mbe' is the wordplay.
'ripping' is an anagram indicator.
'new' becomes 'n'.
'n'+'option'+'mbe'='noptionmbe'
'noptionmbe' with letters rearranged gives 'EMBONPOINT'.
'for' is the link.
(Other definitions for embonpoint that I've seen before include "stout" , "Stoutness" .)
