Armpit onigiri is a bizarre take on the classic Japanese snack where cute girls allegedly press the rice using their armpits and infuse it with their pheromone-containing sweat.

The origins of armpit onigiri, aka underarm onigiri, are not very clear. Some sources claim it was inspired by an iconic scene in the manga Mahōjin Guru Guru (Magicle Circle Guru Guru), where an old man assists the protagonist by rolling rice balls with his armpits. This theory is supported by the plethora of armpit onigiri anime-style artworks that can be found online, but as for how the bizarre treat transitioned into real life, that still remains a mystery. And it was weird enough to know some people are actually trying armpit-rolled rice balls in their own homes, but apparently there are restaurants that proudly serve armpit onigiri to customers willing to pay 10 times their regular price.
