Kleptonomy 

Kleptonomy is a system of capitalism where the rich steal from the middle class and the poor and call this a good thing. To achieve kleptonomy, taxes are cut and social programs eliminated. Also, a kleptocracy is firmly established with the rich, to whom being rich requires any means necessary to amass additional wealth. Enough is never enough.

Similar to Kleptocracy, which is a government or state in which those in power exploit national resources and steal; rule by a thief or thieves. (Dictionary.com Unabridged

Our governor is espousing a kleptonomy by taxing the pensions of state retirees in order to balance the state budget, decreasing money for education and the poor, and providing tax cuts for the rich.

Kleptogamy 

Kleptogamy ( derived from the Greek klepto ("to steal"), and gamos ("marriage"). is a behavior pattern in which males which lack attractive characteristics attempt to mate with females by means of deceptive behavior. Kleptogamy is seen throughout the animal kingdom, but is most often seen in humans.

Common examples of Kleptogamy among beta male humans include pretending to be homosexual in order to gain the trust of a female, or claiming to be a feminist in order to signal their submission to the female, and attempt to trick her into believing the male to be virtuous.

Males that employ kleptogamy have been found to have a much higher tendency towards being sexual predators due to their inability to attract a mate through ordinary means.

Kleptoromantic 

A person who can only feel romantic attraction to someone they stole from other potential suitors/existing partners or who stole them from other potential suitors/existing partners. The sexual counterpart to kleptoromantic is kleptosexual.

Bob is telling Joe about a girl he is romantically interested in. Joe does not seem interested in this particular girl at first but when the girl starts flirting with Joe, he suddenly feels romantic attraction to her merely out of knowing that Bob wanted her first and that he would essentially be "stealing" her from him if he were to pursue her (assume that Joe's feelings for her are genuine and that he isn't just pursuing her to mess with Bob). This would make Joe a kleptoromantic.

An example of a kleptoromantic in popular media is Lilly from the film "Alpha and Omega" (2010).
