To take the upper hand in a situation,
by forcing the other person to face the
consequences of your actions.

Another way of saying:

to win by making someone else the loser
to give someone the losing hand
to give someone the raw end of the deal
to give someone the short end of the stick
to give someone the runaround
to give someone the shortest straw
to give someone the shaft
to take someone to the bank
to take someone to the cleaners
to really take a bath on this one
to pull one over on someone
to kick a friend in the nuts
to get your back scratched but not scratch theirs
to bend someone over the barrel
to have someone's balls in a sling
to do someone from behind without a reach around
