The most badass group of motherfucking gangsters Upper-Middle Class Nassau County, Long Island has ever seen.

OBM 

Old Black Man. Elderly African-American gentleman who drives an old Cadillac, sits on the porch with his OBM friends talking about the good old days when kids respected their elders and didn't hang on porches and street corners like they do now, has a raspy deep voice, looks a little too long at young women passing by, and smells faintly of cigarettes even though he quit years ago. Often seen wearing an old pair of pants, buttondown shirt and a Kangol.

When I brought my girlfriend home with me after school one day, my grandpops and his OBM friends were sitting on the porch playing checkers, looked at her, and slapped me on the back.

Obmama 

Obama and his mama put together.
Greatly decreases the amount of words needed to say
when wanting to talk about Obama and his mother.
Can also be used to talk directly about Obama's mother.
Usually will be used with a curse word before though.

Fuck Obmama! - Talking about Obama and his moma
Obmama is soo fat! - Just his mother
Obmama makes some good azz chikayn! - Obama and moma
Whens da last time u seen Obmama?
