A "Bottom Baby" is a baby whose head was crushed while in the womb.

This is caused by a mother having twins and the baby on top crushes the baby on the bottom, AKA Bottom Baby's head.

A bottom baby is a baby that was conceived via anal sex. Although highly unlikely, it is possible for a sperm to reach the egg while a couple is having anal sex. For example, if the male pulls out when he cums, and unloads all over the females arsehole, some sperm can get into the vulva and thus a bottom baby is created.

If a person ever finds out that they are a bottom baby it is devastating to that person.
