Frequently used in rap, F&N is often found in more violent or creative rhymes or verses. However, its origin is fairly simple so read on.
F&N stands for Fabrique Nationale Herstal. While it might sound like some fancy luxury clothing brand, it is a company that builds high-powered guns that penetrate bulletproof vests. So when using F&N, you are referring to high-caliber and dangerous weaponry. Use this slang by following our examples.
“You better stay away from the streets, especially those with F&Ns.”
“Gang wars were pretty messed up because they used brutal F&N as weapons.”
