There’s all kinds of ways to celebrate a walkoff “sayonara” hit in baseball, but this is the first time I’ve seen kancho being used. For the uninitiated, kancho even has a wiki entry:
Kancho (カンチョー kanchō?) is an act often played out 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. It is similar to the wedgie or a goosing, although the latter acts do not involve direct physical contact.
Hiyama gave Yano (a Hoshino Japan Olympic team member) a kancho on the field after the latter hit a game winning double in the bottom of the 10th to break up the scoreless extra inning game and win one for the home team.
Japan, Hockey, Baseball, etc.
