PBM
Acronym for Perfect Bowel Movement; a bowel movement which vacates quickly and smoothly without the need for exertion, leaves no mess behind, requiring no wiping, and leaves the sitter satisfied.
Some believe a certain (unknown) combination of dietary habits is the key to a PBM.
1. "I'm on a journey to achieve a PBM!"
2. "PBMs are good for the environment, as they waste no toilet paper."
3. "Wow, after that PBM I feel like I can eat a whole pizza, but that may ruin the chances of a second PBM."

PBM
PBM stands for plain and simply, Professional Black Man

This involves an African American coming off as a incredibly professional looking individual.

Things that help

- Always calm (always)
- Stands out among his crowd
- Professional attire
- Great intelligence
- Lead Role (if not he sure as hell makes it look like he is)
Morgan Freeman is currently the king of PBM's, this cannot be debated.

If the torch was ever passed, Don Cheadle would receive it.

Jeff: Samuel L. Jackson is a PBM.
Joe: Samuel would be put in the BAMF (Bad Ass Mother Fucker) category, go watch Pulp Fiction.

Andrew: What about Denzel Washington?
Joe: Denzel is in a league of his own.
Andrew: True, hes a wild card, he can go from BAMF to PBM whenever he wants.

Do you have PBMS?

COMMON SYMPTOMS:

- you work your biceps, chest and abs religiously but nothing else

- You have big biceps,chest cut abs but have scrawny shoulders bird legs and no back and flat triceps

If you or your friends could be suffering from PBMS there's really no cure by now you probably had SBS or suffer from douchebageritis
Guy 1: dude do u walk on your arms? Your legs are scrawny!

Guy 2: shut up I can curl 100 pounds

Guy 1: how much can squat

Guy 2: I don't squat those don't work my chest or biceps!!

Guy 1: oh no! He has PBMS I better warn his parents and loved ones before It transcends into SBS or douchbagitis

We've got the MILF term. It was time to have the opposite. A PBM (for Paper Bag Momma) is a mom so ugly, that even the idea of touching her is disgusting.
dude #1 : What's up?
dude #2 : Tonight, I've a rendezvous with a MILF I met on the net.
dude #1 : A MILF? you'd better expect a PBM.
