P.F. Gene
The P. F. Gene is when you can’t help but get knocked up. It’s like your body is on automatic. You don’t even need to try.
My mom got pregnant right after she had an abortion. She said the P. F. Gene was too strong.
My friend took the pill every day and still had a baby. She said it was the P. F. Gene.
My uncle got knocked up three times in one year. He has the P. F. Gene.
