A woman who is so eager to get pregnant that she takes advantage of a man in order to get to his sperm.
Example#1: I met this really hot 35 year old women at a party last night. I thought we really had a connection, but it turned out she was just a sperm pirate.

Example#2: Ever since we agreed to have a baby, my wife has turned into a sperm pirate.
