Called upon second couple to bonk: video shot (7)
I believe the answer is:
invoked
'called upon' is the definition.
(I've seen this in another clue)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for invoked that I've seen before include "Conjured up" , "Called upon in prayer" , "Made an appeal to a deity" , "Summoned" .)
