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

In motorcycling parlance the nickname for the Kawasaki ZRX1100R or ZRX1200R (and less often the ZRX1100 /1200S). The rex is a motorcycle that manage to make every rider look cool even if when not on said mount he's exactly the opposite.

A type of underwear with scented, as well as thickened fabric to support the utter grossness of the roast beef pussy underneath. Usually used when an individual's pussy-lips become so swollen that they put off a potent odor that stings the nostril.
When Trenton continued to bitch, bitch, bitch.. Joshua told him to go put on his Rex and get the Fabreez out of the closet.
