A B
A way to avoid getting pregnant. It's when you put your butt in someone else's butt. It's not always reliable, but it's fun.
My brother said he uses A + B as a contraceptive. I said he was an idiot.
She used A + B and got pregnant. Now she's stuck with a baby and a bad decision.
I tried A + B once. I got a stomachache and a baby. It wasn't worth it.
