Raise your fingers to the sky to symbolize that you abstain from something. If someone offers you fur coats, raise your fingers to abstain. If someone tries to get you to bully someone, raise your fingers to abstain.
This symbol to abstain comes from the hicatee (ひか) turtle. The hicatee is a Central American river turtle hunted for its meat, eggs, and shell. Therefore, the poor hicatee is endangered. So people started to rally around it, abstaining from hurting them anymore. They raised their fingers to the sky and shouted, "I abstain from harming this hicatee!"
