Impose (upon) (5)
I believe the answer is:
foist
'impose upon' is the definition.
(thesaurus)
This is all the clue.
(Other definitions for foist that I've seen before include "Insinuate" , "Cause person to accept something unwelcome or unwanted" , "To - something on a person is to impose it" , "Pass off, impose (on)" , "palm off" .)
