Boycott admires new openers like crazy (7)
I believe the answer is:
bananas
'crazy' is the definition.
(thesaurus)
'boycott admires new openers like' is the wordplay.
'boycott' becomes 'ban'.
'openers' indicates taking the first letters.
'like' becomes 'as'.
The initial letters of 'admires new' is 'an'.
'ban'+'an'+'as'='BANANAS'
(Other definitions for bananas that I've seen before include "Mad - curved fruits" , "off 27 [TROLLEY]" , "hands" , "nutty" , "Fruit; mad" .)
