Me and my buddy's code words all have to do with soccer. "like hey do you want to play some soccer tomorrow, or we need to get some more uniforms/balls before we play."

We also used to play quite a bit of Halo 2 when it came out and we would gauge the size of all our hits in halo terminology. Like a medium hit might be dubs or trips. Bigger hits get into the killtactualar, trocity, or killamajoro range! haha, we were such dorks.
