You don't "got" it.

[LunarWeaver]

Let's say my woman refuses to cook anymore. I beat her, obviously, and the next day she has the gall to run away. I then must hang my head out the window, shake my fist, and yell "I'll get you yet!" Sure, I have words like vengeance at my disposal, but this is a fist shake situation.

Well, once I kill her I have to keep it even! Since I previously said get, now I must say "At long last, I got her!" It's informal but must be done.
