Orginated from an Illuminati X song called "Black Hand". Delxue, 1/3 of Illuminati X drops the following line:
"Goodevening, looking like you've seen a demon, not happy to see me, thought we had an agreement?"
When listening to this song, that line hits you, and you will understand, the meaning is basicly: sick, ill, dope etc.
(but in a mobster sort of way)
Nikola: yo have you watched Eastern Promises?
Osama: Ye, that shit was Good Evening
