Oh-no-noknow was referring to a silly post I put on Chatterbank. It was late at night, I was pleasantly ******, so I put a silly post on Chatterbank, saying I am turning into a train. It got funny, friendly responses in the right spirit. But Oh-no-noknow began to follow me around the site and pester me. When I asked serious questions, or gave serious answers, there he would be with his 'choo choo' reminder, trying to embarrass me I suppose. I never replied to him, just ignored him till he gave up.
