A unit of measurement used to define length, weight, power pressure, and currency. These measurements include MicroRex, CentiRex, KiloRex, DeciRex, MilliRex, MegaRex, GigaRex, TerraRex, DecaRex, MacroRex and Rex.

The numerical values for all means of measurement are based on the T Rex. Jaw Pressure, height, width, length, mass, and BTU's are all defined by those directly equivalent to that of a T Rex.
Feet no longer exist, except for the ones at the end of your legs. All previous values of measurement have been eliminated. Making way for the universal Rex. Feet, meters, joules, pressure, miles, grams, liters, gallons, inches, watts, all of it is now a Rex

A nigga and a person who Ludacris wants to slap.
I know it's strange
But my brain's gone really insane
And I'm off the chain
Sipping on a fifth of the Golden Grain
I feel like slappin a Rex today (slap slap)
Slappin a Rex today
I feel like slappin a Rex today (slap slap)
Slappin a Rex today
Slappin a Rex today
