It is the dirty old men that ride busy trains during rush hour in Tokyo. They try to feel of young girls butts.. They get on the crowded trains because there is nothing the girl can do. She is trapped. Gitchobutts are nasty, vile creatures and will get a girls butt at any chance.
Did you see that gitchobutt creature on the train? Yea, he was such a slime ball.. Fuck that creep!!!
