I realize most of my readers are English speakers, so my bemusement will not easily be shared by them. To aid you in understanding why this is a bizarre name for a Japanese company (Lotte) to give a product, I recommend you go to Wikipedia's link that explains what kancho is in Japan. If you don't want to mosey on over there, the short version is it's a "game" (or "prank") in which the goal is to violate someone's rectum to the maximum extent possible with your hands. It is played by immature young people of various ages, but, fortunately, mainly by kids.
The above pictured biscuit was in the Korean market, Han Kook. Though it's written on in English, I'm guessing the name has rather different connotations in other Asian languages than it does in Japanese. My guess is that it is for Hong Kong, Taiwan, Korea, or China. The only thing I'm sure of is that it isn't for Japan. No one is going to want to buy cookies that remind them of having their private spaces rather greatly uncomfortably invaded.
