Like a 'port' on a computer that no longer works,
even though there's a cable in it, used to describe a
woman who lies there doing nothing during sex.
Coined at WPI.
John: Hey, I heard you
fucked that hot
chick you met yesterday. Damn, she must have been good!
Robert: Eh, she was a dead port, I would have been better off with by myself with some lotion.
