Pronounced: Nine Elevened

When you're feeling super good, like you are on top of the world, and some force, probably a stupid bitch, completely makes you do a 180 and start hatin' life.

Like The World Trade Center on 9/11/01. Thus, the term 9/11ed.
You are walking through Wal-Mart and you see a girl you know and you enthusiastically say hi and all you get is a very under-enthusiastic hello.

The conversation amongst you and you're friends might go something like:

-Dude, did you see that?

-Yeah, that bitch just shot you down.

- Man, I just got 9/11ed.

-Nigga, that was some straight second tower type shit.
