STAD Number 

STAD represents the "four bad things" teenagers are told not to do. Each letter stands for one of these things; Sex, Tobacco, Alcohol, and Drugs

An individual gains a point for each category he or she participates in, a 0 being the most pure, a 4 being the most corrupted.

Girl 1: What do you think of that girl in math class?
Girl 2: All I know is that after last night, she has a STAD Number of 4.
Girl 1: No way!

The Günter Number 

32.23*10^32
German mathematicians in the early 21st century came upon this numerical value that, when multiplied by any non-zero or imaginary number, will always yield an incorrect answer. However, if any such value is divided by the Günter Number, the answer is more likely to be correct, but only if previously multiplied by the Günter Number.

Is inversely proportional to the number of Trevors in one LMFAO music video.

Engineering Student: "Man, I knew I was way off that Truss analysis when I multiplied by the Günter Number."

Professor: "Unless analyzing the space-time continuum in a completely fictional world, there is no need to ever use the Günter Number in any academic situation in the near foreseeable future."
