No this ain't MMG, but I am a boss

from Tech N9ne (Ft. T-Pain) – B.I.T.C.H. Lyrics on Rap Genius

Meaning

MMG stands for Maybach Music Group which is a rap label owned by Rick Ross — better known as Boss.
Also the last part refers to the MMG compilation album “Self Made Vol. 1” a song with Ross & Meek Mill appears named “I’m A Boss”
Even though this is Strange Music, Tech is still a boss.

Clever rhyme, the previous line ended Ross, which is the person he refers to in this line.

This could also possibly an indirect diss, as Tech could also possibly be dissing Kanye West in the song.
