PMB stands for Penis Memory Block. It's used to describe the trauma that occurs when a woman's been sleeping with the same man for so long she can only remember what HIS penis looks like and has no recollection of her former lovers' goods.
One day Sandra realised she could no longer remember what her ex-boyfriends penis looked like. Or any other penis for that matter; all she could see was Geoff's...
Abbreviation for Puking My Breakfast; used to indicate a level of disgust and/or disappointment greater than Shaking My Head (SMH) or Fuck My Life (FML).
My idiot friend got back together with his disgusting, stretched out girlfriend. PMB.
A bird crashed into my car and exploded over my windshield when I was driving down the highway today. PMB.
The initials which stand for a group known as "Pensacola's Most Boners" (P.M.B.)
This is basically the males in the city of Pensacola who receive the most sexual intercourse.
PMB may be an acronym, but its meaning is unknown. Many say the phrase has relations to YandereDev, which may be true but, who knows. Many also say the name is not complete unless it is paired with a generic name, such as "Tom".
Despite this list of unknowns, what can be said is that "pmb" is more than just a 3 letter name. PMB is a way of life by which everyone should aim to achieve.
