FBNA 

Full Blooded Native Americans - the word originates in san Clemente CA, but has spread to all of Orange County. I means to get as fucked up as a native american so your alcohol level is full blooded. Then you proceed to fuck non FBNA's up and get mad pussy.

-No way! Your gonna get FUCKED UP!!!

- Thats so FBNA
