A term used for old guys on subways in Tokyo that sidle up to girls and totally violate them by groping them or going as far as to
finger girls wearing skirts with no underwear, I know a girl that happened to and she said that as
disgusting as it was it gave her the biggest
orgasm she ever had...she muffled it by burying her mouth into her arm and leaning up against the door of the train...
Anatta wa chikan deshou!!
Hentai Hentai!! Chikan deshou! Chikan!!!
When something like that is yelled out on the subway it is usually followed by the
guy being escorted to a Koban and arrested...
