Colt Feet

The more correct saying and terminology for “cold feet.” It means to be nervous or anxious about something. It makes more sense than “cold feet” because when a baby horse stands for the first time they act nervous and stumble around for a while. And in reality you have or get cold feet, all you need to do is put on damn socks.
