Mistake Dispenser
A female who births one or more children that grow up to do nothing but disappoint everyone around them. These spawns are perceived as and are most definitely mistakes that should not have been created. Mistake Dispenser can also refer to the woman's vagina rather than the whole person. This implies that the woman may not be a bad person but her reproductive organs have a tendency to spawn mistakes.
Example One: "Oh Josh! You can't have kids with her she is bound to be a mistake dispenser!"
Example Two: Doctor "Hello Ms. Samantha, how is your Mistake Dispenser feeling?"
