Adj: A Ex post facto title for the period of time which passes between the initial meeting in a romantic relationship, and after the relationship has ended badly and the betrayer now finds themselves in the same situation as the one they had originally betrayed.

A+B=AB
AB+C=AC-B
AC+D=CD-A

During the period later to be described as swift symmetry, time has a feeling of moving painfully slow to the betrayed, but after the the greater picture has unraveled it's self, the same amount of time now seems to have flown by.

Many use it to describe the faster actions of Karma. What goes around comes back around.
"Did you hear the girl your ex left you for just did the same thing to him that he did to you? Kinda funny, it's gotta swift symmetry to the whole ordeal it i guess."
