NA

The NA is something that ruins your life and causes stress, and depression. Someone who the NA hits hard has probably been finessed or had finessed someone.

Once the NA hits there's no coming back from it.
That's an NA

NA

Naturally Aspirated. Used in many gran turismo games. A way of making your car faster and overall better performing than stock, without super or turbo chargers. To do this "tune-up", many things can work, lighter parts for the engine and a lighter block. Also increasing compression (ratio of volume in cylinders when at the down stroke compared to the volume at the top of the stroke. Cam shafts with larger domes to hold the valves open longer. High output injetion or carb and also thinner head gaskets and much more. A more costly way of improving performance, but with great return. For ways of increasing power and making your car a weed eater all in one, see NOS .

chevyman- dude, i had no idea a few little things could make my car the shit.
riceboy-yeah, whatever, my car has NOS and it will take your camaro anyday.
chevyman-what is your 1/4 mile?
riceboy-18.67 @ 80 m/ph.
chevyman-you need to shave about 6 seconds to beat me.

NA (said 'N-A') stands for not acceptable. It is mainly used as an interjection or adjective to describe things that are not socially acceptable, or actions that are weird, bizarre, or simply inappropriate in a give situation.

That guy just smacked my ass. NA!
