Usually an asian who is special needs. "Jammers" usually acts like someone with cerebral palsy. His features include a huge chin and looking like a monkey. However "Jammers" does have some talent, as "Jammers" is asian, he is very good at maths and tends to be good at slide tackles. Although "Jammers" doesnt understand the meaning of washing his hair yet, maybe one day he will (you just have to believe).
woah that kid is a "Jammers", look at his abnormally big jaw and his asian personality.
