The first use of this latin phrase was found on a painting thought to be the famous playwright, poet, and scholar- Christopher Marlowe from the late 1500’s. (Shakespear’s time)
Cambridge University found a painting they believe to be Marlowe, and saw this phrase inscripted on the painting.
Because of his continued use of the phrase in his works they assume it is a portrait of him.
A modification of the phrase was also in one of Shakespear’s works.
For Marlowe, the “THAT or WHAT” in the quote referred to his muse. And in most other variations of the quote- the “THAT or WHAT” refers to a passion comming from the person himself wether it be love, or power, fear or hate.
"THAT which nourishes me, destroys me."
I wouldn’t doubt that Jolie knows some of this history as well, and being a person who lives most of her passions, I would believe that she would use this as a careful reminder.

(This last one has a picture of Angelina’s tatoo. Please note this tatoo is about an two or three inches above her “ahem” and she is required to adjust her clothing accordingly for it to be seen.)
It is provocative and a little suggestive if you are sensitive to this.
