Not sure if Europeans or Aussies use the term 'chicken poo' like Americans casually do? My dog freaks out when a loud pedicab or bike goes by the road in front of our house so I told wifey our puppy is a chicken poo. She says you mean dog poo? I said no, haven't you heard of CS before? Neither her or her sister living with us had. So she asked me to explain why the term is used for someone scared or nervous? I told her it is used all the time but she asked how it fits. So, I thought about it and, d*mn, don't really know why it is used or how it fits, just one of those many slangs that are taken for granted and we inherited (my mom probably called me CS a few times maybe that is why it automatically comes out of my mouth). On my road chickens cross the street when they see me coming then speed up, maybe that it is origin. Any of you have a wife that understands CS? Anyone know the origin? I know, not a great topic so please ignore if it doesn't ring your bell.
