FOBFA 

FOBFA: Fresh Off the Boat From America.

(1) A proud but ridiculously ignorant American that visits or moves to an East Asian country with no intentions of speaking anything except English.

(2) An American living in an East Asian country who refuses to learn anything outside of American culture.

(1) Li: Ni hao ma？(how are you?)

Bob: Sorry, I don't want the teriyaki chicken sample today.

Li: Ah, you such a FOBFA!

(2) Ming Ming: Happy New Year Friend!

Bob: Damn, you need a new calendar. The ball dropped a month ago. Rascal Flats stole the show.

Ming Ming: You numba one FOBFA in all China!

fobface

Think "Perfect Stranger" meets "Coming in America", fobface is said of someone totally unaccustomed to American idioms and American way of life.

My roommate is from Cyprus, we call him fobface because he has no idea of what's going on.
