Get the Self-opp mug.This is a word that means to f*ck off. If you are wondering what each individual word means, here you go. Elisy doesn't mean anything, ose means Carbohydrate, polar means pole, and opp, means two things on opposite sides. It means to f*ck off because if you take the bottom half of the bottom line POLAR OPP and put it over the bottom half of the top line you get f*ck you. This is found on t-shirts
