why do southerners do it doggy style ? so they can both watch nascar
Why do you focus on southerners?
Because they are all inbred and stupid.
While there are many jokes about people from the south having sex with family members, it can be hurtful to them to think that they actually are doing it. Those stereotypes are based on those types of jokes. You would be grossed out if people implied you had sex with your mother or sister.
