I had a friend in my 20's, a guy who was so shy of woman that he could barely speak in their presence. He used to boast loudly to the other guys about his penis, however, when women were not around, and he referred to it as "Little Wally". This occasioned a lot of amusement among the rest of us, given the fact that "Litte Wally" had clearly never been let out of the stall, let alone been put through his paces on the track itself.
