Kancho is for the birds
when i worked at the elementary schools, there wasnt a day that went by without feeling many tiny fingers being crammed up my butthole by all the little children.
kancho actually means 'enema', and i kid you not, on a sweltering, summer day in an old japanese public school with no a/c, the last thing you would ever want is someone to violently touch your butthole...
kanchoing your friends is fun though, and the kancho craze should be passed on to the states. if you have any questions about style, or proper form/etiquette, feel free to ask.
