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.

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!

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?

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.
noun:
"I'm flying this jet New York style, prepare to jump as I'm 9/11-ing this bad boy right into their base."

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

Shorthand for the terrorist attacks in the United States on 9/11/2001 that caused over 3000 deaths. Many were burned alive! I think this tragedy would have been prevented by a diligent and competent president.
9/11 has also spread hurt all over the planet and it ain't done yet. 9/11 has excused assaults on the U.S. Constitution as well, possibly leading to eventual tyranny or oligarchy.

9/11 is four minutes before nine fifteen
Jeez is that the time 9/11 four more minutes and it will be a quarter past the hour.
Time to go to the pub to meet my friends and have a pint.
