look up any word, like fleek:
When Al Qaeda terrorist bastards hijacked planes and crashed them into the Twin Towers, the Pentagon, and nearly the White Whouse. Over 2,000 innocent Americans died that day.
Remember 9/11.

A 9/11 is a sex act in which a man violently and unexpectedly inserts his penis into the anus of his sex partner. This may occur during or outside consensual intercourse.
When I asked Maria why she broke up with Stanley, she said that he gave her a 9/11 after a night of drinking.

9/11 marked the begining of what george bush senior calls "new world order". 9/11 was an inside job and was planned and executed by members of the busch administration, cia, military and other government agencies. i know this sounds crazy but think about it. how could 19 towel heads take over 4 planes, TURN OFF COURSE FOR ALMOST AN HOUR,manage to waltz into the most protected airspace on the planet ( the pentagon ), and just manage to fly planes into buildings without being intercepted by military jets. seriously, theres so much more to it. i suggest you watch "Loose Change Final Cut" or "9/11 Ripple Effect" both found on google video. doesn't matter what your beleifs are, watch these vids and you will see that 9/11 wasn't as advertized.
- 2 drone (fake/disguised) planes with extra equipment attached to the bottom possibly a missle or a pod hit wtc buildings 1 and 2.
- the pentagon was not hit by a plane, but evidence leads to the possibility of a cruise missle
- plane headed for the white house was being tracked by the military but then overthrown by passengers and purposely crashed it into the ground as a sacrifice. although theres no plane to be found in the crater, just tiny bits of plane spread over an 8 mile radius. shot down? dick cheney says no, evidence and common sense says ya.
- 9/11 was a pretext for invading afghanistan and iraq, the government lied about weapons of mass destruction and terrorists. why are we in the middle east fighting?

verb, pronounciation (to nine-eleven): to lie to somebody, partially telling the truth with the purpose of deceiving somebody.
When your girlfriend comes back from a holliday, and you suspect her of cheating on you, you say:

Listen up, you better tell me what happened and don't even try to 9/11 me!

The act of commandeering an aircraft in online Battlefield 3 matches with the deliberate intention of crashing them into the enemy base. Preferably jumping out at the last minute saving yourself but dooming everyone else to a fiery death.
"I'm flying this jet New York style, prepare to jump as I'm 9/11-ing this bad boy right into their base."

"Did you see that? Just totally 9/11-end like 3 people"
