An allusion to Heroes' character Dr. Mohinder Suresh in episode "Cautionary Tales". A
gullible, spineless man, Mohinder betrays his
partner and gives him a
bullet in the eye.
To go mohinder on someone is to betray them after claiming to be their friend, usually under the influence of an external factor that takes advantage of spinelessness.
Those
poor Native Americans never stood a chance; the
British colonists pulled a mohinder on them before they knew what happened.
She's going to go mohinder on her
husband if he wins the lottery.
