Fresh mint I repent getting chopped up (11)
I believe the answer is:
impertinent
'fresh' is the definition.
('impertinent' can be a synonym of 'fresh')
'mint i repent getting chopped up' is the wordplay.
'getting' means one lot of letters go next to another.
'chopped up' is an anagram indicator.
'mint'+'i'+'repent'='mintirepent'
'mintirepent' anagrammed gives 'IMPERTINENT'.
(Other definitions for impertinent that I've seen before include "Cheeky" , "Irrelevant, impudent" , "Saucy" , "Bold" , "Fresh" .)
