Crossword Genius

Prosper like the party bore (2,4)

Ross

I believe the answer is:

do well

'prosper' is the definition.
(thesaurus)

'the party bore' is the wordplay.
'the party' becomes 'do' (do is a kind of party).
'bore' becomes 'well' (I've seen this before).
'do'+'well'='DO WELL'

'like' is the link.

(Other definitions for do well that I've seen before include "Flourish", "boom".)

I've seen this clue in Sydney Morning Herald.
