a name short for Elizabeth in the case of females and short for Joseph in the case of Italian men. A "Beppy" is also a special tampon made in the Netherlands that really gets all up ins so you can have sex during your period.
"Oh man, that girl Beppy is so awesome and beautiful."
"Hey babe, let's have sex. Yea, I know I'm on the rag, but it's okay, I put in a Beppy."
