kan-csó :))

Kancho (カンチョー, kanchō?) is a prank often played in Japan; it is performed by clasping the hands together so the index fingers are pointing out and attempting to insert them sharply into someone's anal region when the victim is not looking.[2][3] It is similar to the wedgie or a goosing, although, as compared to kancho, those latter-mentioned acts do not involve physical contact which is quite as intimate or direct. A Kancho is often executed simultaneously as the offending party loudly expresses the second syllable of "Kan-CHO!"
