I insisted on calling them this throughout high school because I thought the word hoodie was dumb. Tbh I was probably annoying about it. Eventually I caved, but I still think hoodie is kind of a dumb word. So is jumper for what it's worth.
I've heard of this but never experienced it. I always got verners for an upset tummy... so now it's basically ipecac for me. Can't have any ginger ale now actually.
