Eric Fishel is a Peniscock
term used for somebody stupid/ignorant or annoying, or a man with two wieners that can pleasure a girl very good through both holes, but only has one big nut.
A girl saying "wow that peniscock was good last night, my anus AND vagina hurts." Or a dad saying to his son "go clean off the the kitchen table you peniscock!"
