woman who lies about her birth control status.
A Sperm Thief is a Female that will tell you she is on the pill in order to have unprotected sex to produce offspring.

Get the Sperm Thief mug.
A whore that lies about going on birth control pills and lies about her vagina burns all because of the latex condom and that she's allergic to it to make herself pregnant so she can have many babies from different fathers.
Jack: Hey Martin, did you have a nice shag with that Leighann?

Martin: that Leighann told me she was going to go on birth control pill and I found out she is pregnant.

Jack: wow, trouble is you don't know if you are the father or not because she is a sperm thief and a whore. I'm sure, she has done this to plenty of others.
