A stinky pum is a vagina that smells profusely. So smelly that you cant go down on it without gagging or feeling nauseous.
During foreplay with my mother, I discovered that she has a stinky pum.

You're with a girl, and you think "whats that smell", you realize it's her stinky pum.

Something fishy is going on here, must be this girl's stinky pum
