I want to go to Japan.

Kancho

Kancho (カンチョー, kanchō^?)^[1] 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, the former 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 emphasizes the second syllable of "Kan-CHO!".
