Props to Rihanna she clearly likes pain because getting a regular tattoo where a machine is used can be painful but Rihanna took it a step further by getting a Traditional Maori Tattoo the process is completely different the skin is carved by uhi  (chisels) rather than punctured, This leaves the skin with grooves, rather than a smooth surface and looks painful as fuck!

check out RiRi getting her new tat!
