na!

When lifting up a middle finger, Hong Kong Cantonese tends to utter the word 'Na' or 'Naa' together. Its origin is unknown, but doing middle-finger without saying "Na" is like a woman turning pale.

1. Naa!! (with middle-finger)

Let me tell you. When you call someone nas, it means that they are the lowest forms of life to walk upon this planet.

Can be spelled like this by retards:

Niss, Nass, nis, nyss, nis

"You're such a nas"

"What a nas kid"

"Reece Leggett is such a nas"

"Johnny Brooks is being nas again"

"wow like... Louie Walker is the definition of nas"

Naturally aspirated, reffering to cars that draw air directly into the cylinders rather than using compressed air from a turbocharger.

Gotta love that naturally aspirated Civic.
