On a scale of 1 to 10 a girl that is a 10 will have a vagina stench of a 10. This is called a direct relationship. An example of an indirect relationship would either be her attitude or intelligence, If she is a 10 then her intelligence would be a 1. If one happens to come across a girl with 10 looks plus a 10 personality chances are likely one should run do to the fact of vaginal inflation.
"Bro I went down on a chick and it smelt like roses."
"So you ate out a fat chick?"
"....How did you know?"
