g is the acceleration applied by Earth's gravitational force (for masses much smaller than Earth's, that are pretty close, i.e. essentially everything you typically interact with) and is approximately 9.81 m/s^2
Maybe to elaborate: Its the worst format because its used for all kinds of things that are not "out of line". The original dialogue fit well to it and I liked the scene, but how is it out of line to make a silly numbers joke?
Now if you made some politically incorrect joke with it, sure. But this, no, terrible execution.
g is a constant with units, so it can be expressed by different numbers. I think this works better with pie, 3.14, and 2.72. Unless the original quote uses "pig"…
