NFC, an acronym for "No Fat Chicks", can be used in multiple ways. It can be applied to simply represent a woman with large body mass - such as "did you see that NFC", a label - such as "NFC Emily", or as a literal translation of its meaning; "Come check to my party - NFC!"
While derogatory, its generally considered good taste not to tell NFC's what the acronym means. If confronted as to the meaning by a whale-like female, come up with a definition; "No fucking clue", "Nice facial caricatures", etc. It's imperative you dont let an NFC know what the definition is - lest you be sat on by a large mass of carbon, water, and ugly.
"DID YOU SEE THAT NFC? MOBY DICK AT 6 O'CLOCK!"
"Ok - invite people to the throwdown, but NFC"
"I enjoy watching NFCs fight; especially when its full contact. Its like a cheap version of pay per view sumo wrestling"
