2. 'Sour' is for the taste. Sometimes it's a good sour other times its a bad sour (explained below) The 'baguette' part is for the all slits and ridges which appear on actual baguettes
3. Try to say it around food. It is a very convenient and sometimes comical way to discuss anatomy especially if the topic is discussed around food, or you are around any type of sourdough. It may also be sparsely used around polite company provided they are not in-the-know
4. Not always a bad thing. It can, but DOES NOT neccesarily, mean a bad or stinky vag. See 'sour vaguette' or 'sour vagette'. When generally used it just describes that body part and the taste/smell is neutral, unless described further
5. Good sour...bad sour. Just like a real baguette there's good sourdough and bad sourdough. So times it hot, moist, fresh, soft, and it smells really nice. Obviously you are really in the mood for it. Other times it's old, hard, crusty, and smells dusty. That's when you decide that you've had enough for one day. Keep in mind that this is usually the same damn baguette we're talking about here: it's often subject to change without notice
6. Bottom line. Remember our appetite for a baguette is based on two things: what particular smell the bakery is producing that day and how much of it we've had already!!
also called 'sourdough baguette' which can be abbreviated as 'SDB'
