FNC is a
short abbreviation for "Fuck
Niggers Cannon", a cannon so
big, it blows up all of your competition into one million bloody chunks.
Can be used as a superlative to compare anything that is ridiculously huge for no apparent reason.
Ex 1.
Bushkers: "Object 292 is coming out to
grind in WT, it has a 152mm FNC"
Harteyk: "Fuck Niggers Cannon, we are grinding now!"
Bevo: "Bwąěąãěęėėéëêèèhhh"
Ex 2.
S: "Fuck Niggers Cannon is tesseract, in my context, Fuck Niggers Cube"
O: "Comically vrilled out lol."
