Faf

Relating to someone that is immature and believes "farts are funny" or does other acts of being not mature. Tends to be major noobs that think they're good at lacrosse and drop-shot in the call of duty series. They think they're word life because they use the scar-h and the G11 assault rifles. And they call everyone "Mon" or finish names with "zo" ex: Mallory "Malzo" original fafs were at Lorne Smith lax camp. Bad to be a faf

Kyle Mon, DarthFadder, TastyxMe10n, James "skeetin" Beaton tend to be fafs. Also other tasty and frosty clan members. Kwalk=ney Anel
