A quote from the movie Gone With the Wind. In those days swear words never came in big movies and the director was in trouble. Before the movie was released, he had an option to either change it, or pay $5,000 (which was worth a lot!). He payed the fine of $5,000 and it the quote became famous, it topped AFI's list of top quotes.
There's even a wikipedia article about it that I can't link to because it's too long.
when someone is ruining something and telling you that what you are doing is wrong, not to help you out, but for no apparent reason. As a response you tell them to not jerk off on your breakfast.
I was having a great morning, but then Benji had to ruin my morning by telling me that the Giants were 1-7 so I told him "Please Benji, from now on, Don't Jerk Off On My Breakfast"
