San-nakji

Idiot Food.

San-nakji (also known as Sannakji and Idiot Food) is a Korean style Sashimi dish that consists of dead raw octopus that is chopped and traditionally served drizzled with sesame oil, but is served instantly after chopping when pieces that are still in motion. Served while the octopus tentacles are still wriggling, the food poses a safety risk and people are advised to cut it into smaller pieces and chew thoroughly before swallowing. Why is this dish a "thing?"

Because being cool in front of your shitty friends is cool.
