look up any word, like blumpkin:
is a capacity of accuracy from within a light beam when interchanging mediums, not to be confused with refraction, this constant is to 8dp 1 and should be used to multiply the angle of incidence thus providing a far more accurate result. as stated by Best's law of reflaction.
Bests constant of refrection.

X degrees x #(Bests constant of refrection) = X degrees to greater accuracy.

Can be anything. Also known as the reflection of yourself in someones eyes.

Can only be used while on drugs, sutch as weed,shrooms, alcohol, etc.
