Self described as 'relentlessly mediocre', a jk (AKA 100% Pot Stirrer) is blissfully unaware of how exceptional he is. His logic, pun-worthiness and sexiness are solid 99 material making him a legen- wait for it (and watch out cause lactose intolerance) - dary catch!! Underneath the cruisy and INTP exterior, he is jacktually very loving, generous and is extremely capable in creating vivid and touching written work. And his toasties are platinum star level!! Watch out though: High odds of contact and stepping. I luff yew jk. What doing now?

Stands for jin kie
