Provoke using popular quote (6)
I believe the answer is:
incite
'provoke' is the definition.
(inciting is a kind of provoking)
'popular quote' is the wordplay.
'popular' becomes 'in'.
'quote' becomes 'cite' ('cite' can be a synonym of 'quote').
'in'+'cite'='INCITE'
'using' acts as a link.
(Other definitions for incite that I've seen before include "Arouse to action" , "Provoke - stimulate" , "Whip up" , "Trigger" , "Encourage to action" .)
