FNG

2003: "Two agents in a dark blue sedan were waiting for me. One of them, Jim Heekin, took charge immediately, and also put me in my place.

2004: "The other guy is hollering "F-N-G!" He's saying "Your FNG is here!" And I didn’t understand what FNG meant. I soon learned: Fucking New Guy. Or we called them Cherries, meaning brand-new guy in Vietnam." — https://web.archive.org/web/20050313164139/http://www.nyfolklore.org/pubs/voic30-3-4/warstr.html

2009: "The FNG here says that we have too much ammunition." District 9
