yeah what's up w that. jackjack sounds like what they call the russians with the same first and middle names. and then there are several versions of the same so they give them nicknames. it's actually johnjohn which is efram eframavich but there are big families and lots of kids all names the same thing. lmfao. so there was jack cheese and jackjack etc - and there was one they nicknamed speed because he was cropped after polio. so anyway... lmao.
