An urban legend around Vermont. Shinski was once seen running up a ski mountain barefoot, trying to find his New Balance snowboard boots. Shinski has been the talk of the state since, with many people trying to emulate his actions. One can hardly walk into a ski lodge without hearing his name.
Actions committed by people you thought were friends when they no longer have use for you. First, they will ignore and exclude you (shun) and then cast you away (dump) when they are finished with you.
Tolly just put the shun and dumpon someone again. When he is done with someone, he is done.
