Crediting somone else for your action without their consent, eventually making you look like a great, compassionate, caring person without having to tell anyone.
I have a crush on my sexy neighbor so I scraped the ice off of her car in the morning after I had done the same to my car. I later told her that it was her Roomate who scraped the ice off of her car. When the sexy neighbor thanked her Roomate for the nice gesture, her Roomate told her that she actually didn't clean off her car and that it was the handsom guy (me) next door. my act of being recresent led to the sexy neighbor realizing what a great guy I am without me having to actually say a word. The sexy neighbor then wanted me because of my recresent behaviors.
