Nismo used to be a combination or the following words: Nis- is for Nissan, -ism is for belief, and the red "O" is the red sun on the japanese flag... so basically it's Nissan's Belief in the red sun... they once said that the Nismo vehicles are only to be the top of the line remade vehicles from Nissan/DAT Motorsports to represent the all mighty sun god that they place amoung their nation's flag, and only those worthy of the true Nismo title gets the badge GT-R... but after a long while, people started to think that the idea was just too cheesy so they simply remarked Nismo to simply be Nissan Motors...
I am proud that I drive a Nismo car...

A sticker widely seen on the back of ridiculous looking cars everywhere. Usually mounted across the cars front/back window giving it that badass finish. Owners of these cars can't actually drive them without parental supervision and more than often end up as road accident victims. Can see paired with flame stickers and V6+ stickers.
John thought his car was the shiznit and would get all the girls at school, for he had stuck a Nismo sticker on every side of his car imaginable.
