An elementary school boy in Tokyo carried out a flawless finger prod into a classmate’s rear during the lunchtime break late last week.

The attack was launched as the victim stood defenseless serving up bowls of rice for his fellow classmates.

“One minute I’m trying to evenly divide up the rice, next minute I’m receiving a good kanchoing,” the victim said.

The teacher was absent at the time of kancho, stimulating maximum classroom excitement.

“I’ve kanchoed a lot over the past few years, but this has to be one of my best yet,” the boy said.

Students are now on high alert, with classroom walls now becoming hot property.

Classroom fashion is now expected to trend toward baggy pants over the coming days.
