Get the FMmug. An online saying that stands for Fat Mexican. It isn't said very often and only the white people that know about it say it when they are playing in online games with Mexicans. Mexicans usually reply with "do you wanté an orangé?" or "Tu es una borradora del Domingo Républico de la quarté"
