Custom-built: Here, you are turned on by how ungrateful you are. You love reminding your lil' victim of everything he has done for you, everything he has given you. Maybe he has done you ample favors, maybe he has given you all this money. The more he has done for you in the past, the more you are turned on by how ungrateful, selfish and evil you are. You enjoy telling your victim that crushing a sweet, innocent man who has helped you so much is way more fun and more pleasurable than just crushing any man, or even a rude, bad man. Etc. And then, of course, you crush him under your sole or between your toes. ;.
