meat to scene ratio 

An unit of measure identified and studied by the philosopher Birdman, used primarily in his extensive scientific studies in the field of cockology.

It measures how much meat (penis) is present in a given scene, facilitating the analysis of the subjects in said scene.
Being a quantitative measurement however, it treats all meat (bbc or otherwise) the same.

According to lost journals by the philosopher, the ratio is calculated individually for each female subject and care must be had in cases where double(or triple) meat specials are at play.

signal to noise ratio

The amount of screaming one generates, in proportion to the amount of real content they are communicating.

People who grow up in empty households (often with a lot of older people) feel as though noise and signal are in direct proportion, which causes them to pump more noise in the hopes of generating more signal.
