NOS
Noun. 1) An acronym for the brand name 'Nitrous Oxide Systems'. NOS produces a chemical known as nitrous oxide, often used in the performance optimization of car and motorcycle engines. The chemical (N2O) breaks up upon contact with air, releasing extra oxygen into the engine. This often means that oxygen detectors in modern cars pick up the extra oxygen and add more fuel to the a/f mixture. This means the engine will pack a harder punch than it typically would, in the form of an instant flywheel horsepower gain. 2) A buzzword used by the illegal street racing comunity (often populated by rice burners), to make one's car sound fast. Many misconceptions have arisen from the term NOS, particularily founded by the film iThe Fast And The Furious/i. One misconception is that NOS can be installed on any car, and with the push of a button it will result in an exponential gain in speed. Another is that NOS iis/i nitrous oxide; NOS is only a brand name. Nitrous oxide can only be installed on some engines, and does not necessarily mean a huge gain in speed. It is NOT activated with the push of a button, most nitrous systems have a throttle trip system that activates the nitrous flow at WOT (wide-open-throttle), in order to maximize potential speed. Another widely mentioned misconception is that nitrous oxide is flammable. It is not. Though any compressed gas can explode when heated, the gas itself is non-flammable.
The Urban Dictionary Tee
The T-shirt was a birthday gift for my girlfriend and she absolutely loved it.

Happy that this tee is comfy and fits well. I wish the sentence was on the back too.

This looks like a weird design but it looks cool
This T shirt is the best piece of material to have ever graced this Earth. The fine quality fabrics and in depth definition, which is professionally implanted on the back of the shirt, which makes for some very interesting talking points. Thank you Pablo Parmesan.
