don't mack on my nine 

A phrase created after some one misheard "back in year nine...".
Now accepted as a faux-ghetto slang term. Can be used at any random interval but works well if some one has offended or insulted you in any way.

Man 1: You're a knob
Man 2: Don't mack on my nine

To come up with ideas, to brainstorm. In a 1993 interview with people magazine, Ronnie DeVoe of the multi-platinum group Bell Biv Devoe explained, "When we sit down and come up with ideas, we call it hootie-macking." Also the name of BBD's second album.

Bell: Yo, we gotta get a hootie mack going, i'm feeling creatively stifled and we gotta record this new album.
Biv: Word.
Devoe: Now ya know.
