A homosapien of the sub-genre "Ginger". See "Ginger" for more info. Though displaying the physical appearance of a "Ginger" they are far less creepy and quite possibly have a soul. Most Jenn Porters are female and surprisingly attractive.
Dude 1: Dang, did you see that Ginger walk by. I didn't even get the shivers or feel cold inside.
Dude 2: Dude, that wasn't a Ginger, that was a Jenn Porter. And she was cute!
