I know that AC usually means air conditioning.
But my brain automatically thinks "armor class" first.
In a similar vein, there's an empty lot near my house with a for sale sign advertising its size, approx. 13 acres.
It says ±13 AC.
Every time we drive by it, my fiance has to say something about how the large field grants such a great bonus to armor class. :)
