Quote me ... "Returning throwing aid!" (6)
I believe the answer is:
emetic
'throwing aid' is the definition.
(an emetic makes you vomit ie throw up)
'quote me returning' is the wordplay.
'quote' becomes 'cite' (synonyms).
'returning' says the letters should be written in reverse.
'cite'+'me'='citeme'
'citeme' backwards is 'EMETIC'.
(Other definitions for emetic that I've seen before include "Medicine that induces nausea and vomiting" , "Something that causes vomiting" , "Purgative" , "Nauseous" , "It would make you sick" .)
