"Don't let her Rose you"

Humorous test of girlfriend instincts. Instructional video here.

It was a test, "babe," to see what kind of partner you are. I'm in a fight, and your move is to hold my arms behind my back? ... Have you seen "Titanic"? That scene where Rose is literally in a lifeboat and jumps back onto the ship so she can be with Jack? Every guy saw her do that, and instantly went, "Well, Jack's dead." That's what you did here today. You Rose'd me.

Later in the thread, some posters discuss:

Q. Can anyone try to explain this behaviour? Any women here who has done this who would like to explain the process that leads you to do this?

A. It's evolutionary. She is slightly disadvantaging the OLD sperm donor to allow the NEW sperm donor to prevail (providing a variety of offspring with HER genetic material). This very dark atavistic/evolutionary impulse MUST be tamed in society
