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 Mug
Haylee My name is haylee sullivan and the mug is describes everything about me and i would rate it at a 5 100% it is awesome

I’m right handed and would’ve liked it better if the handle was on right side with name facing forward instead of having verbiage facing front
girlfriend loved it :) - Ian's Girlfriend
the urge to buy it and write cum on it
Purchased this mug as a Christmas gift. Can’t wait to see the reaction!
This is to test if the Urban Dictionary store rating system is working and not showing fake 5 star reviews.
These are hilarious! Great gifts. Cost seems a bit high but i couldn’t resist.

It’s a great way to store my pencils.
I used this instead of condoms It didn’t work and now my nephew is my son
Ordering was very easy and the delivery to a different address then the billing address was done effortlessly with complete correct order. Was delivered before estimated date which was very exciting. Good job well done by all.
Funny stuff! I wish the mugs cost a bit less, I'd buy more. There's an almost unlimited supply of clever slang.
awesome. came just as ordered.
Nice cup a few words were darker than the rest. But ok
아주 좋은 머그잔 나는 죽은 아버지를 위해 시원한 머그잔을 얻었고 매우 자랑스러워했습니다.
I like the mug, it’s good quality, unfortunately the customization wasn’t correct. I got the “juff” mug and instead of the definition i had a quote from one of my friends as a bit, but it just came with the definition. I’ll still give it to him because the joke still works but I am a little disappointed.
Love the fact that Urban dictionary came up with such an accurate and quick meaning for Binger! Mug was a little pricy but God is my morning coffee so much better in this mug!!
This mug is incredible! It was a great gift for my friend named Jacob, who is definitely gay. (Even though he says he isn't 🙄)

Great mug, she loved it
I'm in a Spanish-speaking practice group, and the phrase "Ajo y Agua" came up, meaning, (more or less) "If you f***ed up, deal with it." (It's a long story, how "Garlic and Water" means this, but that's the fun of it.) Anyway, the Urban Dictionary site with the mug popped up on Google (reading my mind, as always) so I bought one as a gift. It's not cheap as mugs go, but I'm happy to say the mug is VERY good quality, looks exactly as it does online, and is packed in the most securely designed mug-transport box I've ever seen. You can't break it in shipping or reshipping! Also it arrived in just a few days. I recommend this product highly.
i like mug that say words
