Extremely proper individuals eloped when forced (6)

I believe the answer is:
prised
'forced' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for prised that I've seen before include "Forced open with leverage" , "Jemmied, levered" , "Levered open by spider" , "Forced open with a lever" , "Levered (forcibly)" .)
