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
